Hangkai 3.6 / 3.5 hp outboard motor - 10 Things To Know

[@christopherwicks2300]

This video has been so helpful thanks so much I've had this motor for a few months now and use it a couple of times a week and it's not put a foot wrong I used high quality gear oil and changed the sparkplug to a champion one and I only use 98 octane fuel and 2 stroke racing oil at 40-1 and it runs so sweet

[@BoilerDan1]

Good to hear a success story. I’ve got a couple of videos on changing the clutch. It’s not difficult and I took more apart than needed…. But it’ll be part of the routine maintenance for you…. But I enjoy working on it. It’s a simple engine, and that’s a good thing! Thanks for watching and taking the time to comment! 👍👍

[@christopherwicks2300]

@@BoilerDan1 I've not had any clutch issues but my hangkai 3.5 looks slightly different to yours the case is grey, maybe it's a mk 2 or something but the clutch looks slightly higher quality. I found running it on premium gas made a difference and tightening the throttle cable a bit I've got it on a small zodiac dingey and can get about 15 kmph max and 10 kmph (about 6 mph) on cruise on the canal and travel about 7 miles on a tank of fuel, I might also change the propeller and fit a dolphin hydrofoil to it to max out the performance

[@BoilerDan1]

@@christopherwicks2300 that’s great! Thanks again and enjoy your time on the water!

[@ah2347]

In an email I received from the seller that sold me the motor, they mentioned that I should use 87 octane ethanol free. Unfortunately, where I am there is only 91 octane and above. You mention in your comment that you use even higher octane. I am wondering, has your motor ever suffered from the higher octane fuel? Thanks in advance.

[@BoilerDan1]

No, you just don’t want less octane. The ethanol additive can deteriorate the fuel lines. That’s what I had happen. I guess go with what you have available and change out fuel lines each season. With the increase use of ethanol you might find new lines that hold up better?

[@steveevans3853]

Thanks for posting. Great advice. A huge improvement to these motors is to fit a 1.5 clutch spring. The original is a 4k....meaning the engine revs to 4000 revs before the clutch engages.....engages the driveshaft to turn the water pump. A clutch spring from a Honda BF2d or BF2.3 fit perfectly and greatly improves the engine

[@BoilerDan1]

That’s great advice. I replaced my spring with one from a hardware store and it did work, but getting a true fit is a much better solution. Thanks for sharing! And watching!👍👍

[@steveevans3853]

@@BoilerDan1 In my opinion there are plenty of ways of extracting more power out of these engines, the carbs are not the brilliant and exhaust is functional at best..The leg and drive is from a 2hp Yamaha and being a short stroke oversquare engine has plenty of low down grunt

[@BoilerDan1]

Shame that I didn’t have your knowledge from the start of my adventure!😂 Thanks again for sharing 👍👍👍

[@ah2347]

Is the clutch spring easy to replace? This is very interesting, thanks for sharing.

[@BoilerDan1]

I’m not a mechanic by any means. Yes it’s an easy fix. I couldn’t find a lighter clutch spring so I used one for a hardware store that I was able to clip on. I think you responded to Steve Evans comment, so take his advice and search for 1.5 clutch spring. If you watch the video I posted on replacing the clutch spring you’ll see what I did. It worked much better than the original one. It’s way too strong. Thanks for watching 👍

[@oldmandoingstuff8997]

Boiler Dan, yes Gators we have not many jus a few here in Montgomery County, I'm on look out for sure, . Tks for tips I ordered the latest plug u changed to after the champion.. I'll post here in a month or 2 when I get the tandems runnin on the boat. John

[@ScreenMasters369]

Hows the engine going?

[@PopzThompson]

Great tips Dan, especially like the idea of bees wax on that starter cord.

[@BoilerDan1]

Thanks goes to my Grand-dad (Grandfather), who showed me that on a very old motor that he would hand wind a rope around the flywheel to pull start it! Thanks for watching!

[@BillyGirlardo]

I'm real close to buying the 4 stroke 4hp off Amazon so thx for your checklist!

[@BoilerDan1]

In hindsight that’s what I would rather have purchased. I think the 4 stroke is the way to go. However, special note: it can’t be laid down sideways as oil will leak into the cylinder and fowl the plug. (So I’ve been told). You can remove the oil and refill it at your destination if you need to transport it laying down. I’ve also been told that you can lay it down at a slant on one side, I just don’t know which side is okay? Thanks for watching and taking the time to comment 👍

[@Manuel_Z_Kayaks]

I'm buying one new/unused tomorrow. Thanks for the tips. Another tip for small motors... LEASH/CHAIN THE MOTOR TO THE VESSEL. In case it comes loose or someone tries to swipe it

[@BoilerDan1]

Good luck with yours. I enjoyed my journey but it does take some tweaking. I think mine would have preformed better on a small hard shell boat. The raft was a bit spongy causing me to lose thrust. Thanks for watching 👍👍

[@lopez9964]

​@@BoilerDan1is the 3.5 HP one kinda the same thing. Thank you for the video as well

[@BoilerDan1]

Yes, almost same thing. I think it’s just a previous version. It’s a bargain as long as you don’t mind playing with it 😂👍👍

[@28ebdh3udnav]

So in other words, it works when taken care of... Right? Thinking of buying a small inflatable boat and attaching this

[@BoilerDan1]

Yes. But it does require paying attention to the little things! I think the motor itself is good. It’s the clutch and fuel lines that require regular maintenance. Regarding the raft, I’d recommend a better one than what I used. The motor mount is too soft causing the motor to tilt and losing thrust. Or work on a better motor mount so it’s attached to the solid floor. Thanks for watching 👍

[@robertusa1234]

I've had the same problem with the cheap Chinese 2-stroke generators first thing you have to do is get rid of these spark plug that comes with it and change out the fuel line

[@BoilerDan1]

Good to know I've done the right things ;0)

[@geoffb108]

All of what you said is correct. I learnt this by myself when i bought one. From new mine had a leak from the water jacket over the cylinder which sprayed water over the engine. I tried to return it via eBay but was told they didn't want it returned and gave me a full refund. I tried numerous methods of sealing the leak to no avail. I gave it to friend who also tried to fix it. He used it for a few week before giving up. Not really a good design and poor quality. Wouldn't trust it more that swimming distance from shore

[@BoilerDan1]

It’s great that they refunded your money ! I’m surprised you weren’t able to correct the cooling water issue as it’s a very simple system. You could probably have just disconnected the water tube and just use it as air cooled. There’s not that much water flow. I agree regarding staying reasonably close to land!😂👍

[@pollyrobinson3877]

Thanks for this, Dan. I’ve thrown together an amazon shopping cart based on your list. Really appreciate you taking the time to post this for engine noobs.

[@BoilerDan1]

You're welcome. Thanks for commenting. Hope rains slow soon so I can actually take mine out this year!

[@THELIFEDREAMER.1329]

Hi Dan, thank you for sharing your videos with us, a lot to learn from them. A quick question for you, can I lay down a hangkay 3.6 two stroke motor. Please let me know. Thanks!

[@BoilerDan1]

Yes, it’s the 4 stroke that the oil can leak into the cylinder and fowl the plug. That being said, you’ll want to remove most of the fuel so it doesn’t leak out the vent in the cap, but just having a little slant will illuminate that possibility. I transported mine laying in the back of my car, just kept the fuel tank up on other equipment so it slanted down. Hope that makes sense? But yes you can lay it down. Thanks for watching 👍

[@THELIFEDREAMER.1329]

@@BoilerDan1 Hi Dan, thanks for the answer! I am kind of new on all of this and just trying not to kill my new 3.6hp. I actually have a 4 stroke 9.9 tohatsu too, but with four stroke, everything is different ( transportation, oil,etc) thanks again my friend, great Chanel!

[@BoilerDan1]

You’re very welcome! Thanks for watching 👍👍

[@Apollux]

Related question: can you swing the throttle arm all the way up or down? I’m considering getting one and will have to lay it down for transport in a rectangular space. Said space have enough length for the head+shaft but not enough space for the throttle/control arm in full “use” position. Any information would be appreciated, thanks.

[@BoilerDan1]

Yes the throttle arm will pivot up. Not down though. I chose the 2 stroke for the same reason…. To lay it down on its side. The 4 stroke holds oil an must remain upright. I will add the the exhaust goes out below the water line and that muffles the noise….. the 4 stroke has a muffler. I say that because I wouldn’t use this as a trolling motor….. a lot of sound going into the water. But to get from one place to another it worked for me….. but its not a motor for everyone, as it has some issues. I’ve documented them in the series I made along my journey. 👍

[@upsidedown1986]

Hi do you know how many turns out the carb screw should be from the fully seated in position? Great videos byvthe way very helpful.

[@BoilerDan1]

I’m sorry, I don’t remember exactly…. Maybe 2 1/2? Or 3 1/2? Here’s a video that might explain better: kzbin.info/www/bejne/mYmonXV9YpVphNE

​@@BoilerDan1thank you. 👍

[@BoilerDan1]

1st, Did you add gear lubricant at the propeller gears? It’s shipping without gear oil in the gears down by the propeller (watch my other videos) 2nd, The propeller doesn’t turn at idle speed, you must run at least 3/4 speed for it to turn.

[@richsoliman8394]

Do you think it will move a 16ft aluminum starcraft 1 mph at 3/4 throttle?

[@BoilerDan1]

@@richsoliman8394 Ha, Yes, I’m sure it would manage that task! It’ll do better on that than my sponginess of my raft. Make sure you check out several of the videos I made. The clutch wears out quickly, but replacing or even removing the clutch tension spring will greatly help.

[@richsoliman8394]

@@BoilerDan1 thanks

[@heritagelandscapedallas]

Hey Dan - just below the bottom 1/2 engine adjacent to where throttle cable enters there is a hole blowing exhaust- looks threaded-

[@BoilerDan1]

Hmmm, I’m not sure? But the exhaust system isn’t that sealed a system. If the exhaust vents just above the water line are plugged, the exhaust could flow back upwards. Shame you can’t attach a photo to show more.

[@JeffDeanTheDeanZone]

1. What pin do you remove to fill prop with gear oil 2. What kind of gear oil do you use? 3. What kind of grease do I use to grease the pivot point? I'll ask more questions as I watch this video, so far, it has only been slightly helpful. I knew I would have to put oil in it but did not know where to put the oil and your video is so vague it didn't really help me. 3:14 Fuel Mixture? It's an electric motor. ROFL It runs off 2 24v 120AH batteries wired in series according to the manufacturer's manual

[@BoilerDan1]

There’s just two bolts holding the cap on at the backside of the propeller. Be careful not to over tighten them. Also do not completely fill the area with gear oil. Look closely, there’s a line a little below the top that you fill to. 90 weight gear oil To grease the pivot point it’s just standard automotive grease. You’ll need an inexpensive grease gun to inject it into the shaft. Here’s a link showing me changing the gear oil and the two bolts. Thanks for watching 👍 kzbin.info/www/bejne/hHSkfYdpgrB0e80

[@brujodat]

Great video. I own a Hangkai 4hp 4 Stroke. Can a pipe be added from the exhaust all the way to the water in order to make it quieter?

[@BoilerDan1]

I have sometimes wished I had gotten the 4 stroke. I don’t really know the answer to your question. Maybe another viewer can answer. That being said, I would think that you could, but the noise might reverberate through the pipe? Maybe look into a better muffler? I tried to insulate the housing but took it off due to concerns of overheating…..

[@davebushell8127]

Great info, I would add that on my 3.5 the in tank fuel filter seem to have an inbuilt metal weight and its breaking down leaving a metal paste in the bottom of the tank. I replaced it with an all plastic one with a s/s nut to keep it at the bottom. + new fuel lines. The 3.5 splits into left and right halves and the fuel tank is attached to the half with the sparking plug and carburetor i've swapped mine to the other half for ease of maintenance

[@greyagle]

Can you explain how you swapped it? I like the idea. Pretty dumb having carb adjustments on same side as tank. Should be able to adjust on the fly as needed

[@BoilerDan1]

Hopefully Dave Bushell will see your question and answer. Thanks for watching. Sorry I don’t have the answer.

[@jimdombroski]

What spark plug do you use?

[@BoilerDan1]

I made a follow up video that lists out that information right at the beginning of the video. Here’s a link to that segment: Hangkai outboard motor - Spark Plug Upgrade kzbin.info/www/bejne/gIbEeZ2tf7iaotk Thanks for watching 👍

[@randywall9230]

When I tried start mine the first time it wouldn't pump fuel, took apart the in tank filter and it had a plastic plug in it. Like it was put there intentionally,took it out and am now breaking it in - runs great

[@BoilerDan1]

Interesting! Maybe someone forgot to remove it in production? Be aware that the clutch wears out within a season. I made a video on replacing it. The tension spring is too strong. I changed mine out with one a lot more flexible and that helped. I’ve also seen where people just remove the spring! You would lose idling because the propeller would always spin, but definitely would reduce wear on the clutch. Hope all continues to go well with yours.👍👍

[@HigherSelph]

Where'd you find the gas to oil ratios and break in info anyway? I have the 3.5HP model, which is a little different, but the manual doesn't even mention break in. As for the mixture, it only says "The admixture of this machine at normal usage hour compares is: 30:1. Please press this comparison strictly to prepare the admixture oil, cannot random the changes."

[@BoilerDan1]

Here’s a link to the company website: m.hang-kai.com/en/ Then in the upper left corner click on the multiple horizontal lines. On that page click “News” You’ll find the oil recommendation there.

Specific issue, can't get the bulb to fill with fuel. Change filter in the tank, lines are new, primer bulb isn't cracked, took carb apart to see if debris. Cleaned and reassembled. No luck, Your thoughts appreciated. It's new. Land stranded in Texas.

[@BoilerDan1]

Hmmm, I’m as stumped as you are? Only thing I can think of is switch the fuel lines? Maybe the wrong line is going to the fuel bulb? Other than that, there has to be a air leak preventing the pumping action to work? Sorry I can’t be any more helpful. I just returned from Mustang Island Texas! Indiana 19 degrees last night! Should have stayed in Texas! 😁👍 Last thought: replace the bulb….

[@marcvan]

Hi, Thanks for the video. I bought one of these and am in the process of replacing the throttle cable. Please be advised like everything on this motor it is super cheap and therefor rubbish. Make sure you oil / grease cable every year. Mine was completely rusted. Also curious at the power or lack of it. Mine is a 3.5hp but identical to yours. All brand name 2 strokes have twice the cc so I suspect it is at most 1.5hp. Your thoughts...

[@BoilerDan1]

I've not had any problem with the throttle cable....something to look forward to I guess? I know saltwater would cause some issues like that...But on your advise, I'll grease my cable this spring. I'm with you on the power issue, but I didn't expect a lot of speed out of it. I don't plan on going long distances, so for my little adventures, it's ok. Definitely not for everyone. I appreciate your watching. Hope some of my other videos will be helpful too. You'll need to change out your clutch soon too...I put in a lighter spring and that looks like it will help a lot. (Maybe you haven't gotten to that video yet? Keep watching! :0)

[@marcvan]

@@BoilerDan1 Thanks Dan. Watched clutch stuff. More fun in the future. Yes I run in salt water. I run it in a fresh water bucket after use and hose it down but corrosion still everywhere. I have taken to spraying WD40 over all aluminum motor bits and "stainless" screws after each use Why can't the Chinese make stainless 316??? I note one eBay site has sold 43 throttle cables for the 3.5 for $20 Aussie. I did the lower gear oil change as you demonstrated. Filled to half, ie well below the line . The gears will run through the oil sitting at bottom, so all good. Thanks for the videos.

Helpful tips, wondering if I should try one of these.

[@BoilerDan1]

You should research quite a bit. I’ve made several videos! Probably the biggest concern is regularly replacing the clutch. It’s not that difficult if you like doing that kind of stuff. The clutch spring being replaced with a lighter one would help a lot. Again, not that difficult. I knew nothing going into my motor and I was able to figure it out. It’s also a bit loud. Definitely not for trolling, but from one point to another it’s fine. Thanks for watching and check out all in the series to help you decide if it’s right for you. 👍

[@ChubbyAnts]

@@BoilerDan1 Thanks for your reply, yes I've just watched some more recent videos of yours. And some others in general. Thinking ill maybe stick with a Mariner or Suzuki after all.

[@BoilerDan1]

I agree with your decision! I just wanted something cheap to play around with. It served me well but if you can afford more, it’s a better choice to get better. I think overall the motor’s block is good. But the add on stuff is too cheap. But I like to tinker so it was just right for me 😂.

[@nedflanders190]

I see so many unboxing and reviews of the first time using these and so many other things but never anything else after that I'd sure like to know how it does over a few years. I wouldn't trust it on lake superior but still might hate to paddle back after dark from some of my favorite spots.

[@BoilerDan1]

Your concerns are valid. I made several videos on my experience with the motor. I’ll put a link below. But to be honest, I always went upstream so I could drift back if needed! kzbin.info/aero/PLjMZtm2hvqrOIvLcah1u1V45Y_R-AKeqm I recently turned 71, and my family encouraged me to sell mine, so my journey with the motor has ended. I had fun though!👍

[@BoilerDan1]

Your clutch is worn out. One of my videos shows how to replace. Also might change tension spring while you are working on it. Spring is to tight and causing excess wear on the clutch.

It sounds like the spring or the bolts holding the spring in place are too tight, not allowing the clutch to engage. I think if you watch the video you can try to fix it. Unless you want to try to return it to the seller? It’s not a difficult job to do, and your going to have to learn how to replace the clutch in the future anyway. But it’s your decision to make. Hope it goes well for you 👍

[@thrashenoutdoorstv3675]

Last question..how do I get motor to stay in place so that when I give it gas it doesn't lift out the water

[@BoilerDan1]

The best way is to break in the motor by using it on your boat! I only used bucket because it was in January and very cold, plus I’m far away from lakes. Also if using bucket or barrel, you must keep cool water running in the bucket so you don’t overheat the motor. I kept adding snow! You’ll need to build a frame to hold the motor, so instead, it’s easier to attach it to your boat and take it out on the water running at various speeds to break it in. Doesn’t have to be done in one day, just keep track of the hours of using it. Once broken in, you can go full speed all the time 👍👍😎

[@LuvThyMind29]

Does this thing not come with a hang tag/emissions certificate??

[@BoilerDan1]

No. At least not when I purchased mine, but that was a few years ago.

[@Steve-fz3pl]

Hi Dan, Good info for this little motor. I have a couple of things to add; 1. My pull start and claw pull failed from the beginning, not sure which part failed first. It’s a good idea to take the pull start off and tighten down the claw pull with thread lock. Then replace the pull start with a little thread lock. 2. My throttle grip was loose. Ive tightened it up by removing some material between the joint but need to add a sleeve I think. 3. My 2 cents on fuel. Avoid ethanol fuels and high octane fuels. High octane fuels may use ethanol to bring the octane value up. Hangkai recommend standard unleaded 93. We use standard unleaded 91 for small engines. Use only fresh fuel, only mix what you need, do not store fuel, tip unmixed fuel into a car to be used rather than storing. Ethanol is corrosive to metal parts like the carb needle and seat. It will degrade rubber like the fuel line and internal carb gaskets. These little engines use a rubber gasket fuel pump which runs off the crank case pressure, ethanol will quickly damage this gasket fuel pump.

[@BoilerDan1]

Thanks for your thoughts and good advise. I'm fortunate to be in an area where you can find fuel without ethanol blends. Although my fuel line still rotted out within about 6 weeks. Hope people considering this motor will take the time to read comments like yours as they will have a better overall experience with it. For me, half the fun is overcoming the little problems! :0)

[@MiguelACiriaco-Hernandez]

So I received the gas can that it came with but it's a Lil different where I put the oil in is a little smaller it has a 35 on the side I don't know how much I would have to fill it up to get the perfect blend any suggestions

[@BoilerDan1]

If there’s a line where the 35 is, and it’s towards the bottom of can, you’d put the oil in first to that line. Then fill the can with gasoline and that’s the 35/1 mixture. You could also purchase a container from a Walmart, Menards or similar store that will have all the mixture options you’ll need. Here’s an example from amazon: a.co/d/68bV108 NOTE: You’ll need to estimate to get the 35/1 mix as it doesn’t show the exact 35. But you can go between the numbers shown.

Thanks a lot! Greetings from Germany! 😊

[@BoilerDan1]

Some of the things may have changed as I gained more experience… Don’t need a better air filter. In one segment I tried insulating the sound but that holds heat…. So don’t do that…. Breaking it in is best done just using it on your boat…. Anyway, glad to help. By the way: Small World! My mother’s family are German (Reister).

[@HigherSelph]

​@@BoilerDan1 Thank you. I also asked the seller, but instead of answering, they asked I use the original propeller first 🤷‍♂️

[@HigherSelph]

Hopefully my last question for you 😎 Wondering if your water got really nasty when breaking in. I'm at about 5 hours in and have been using the same large trash can the whole time. And the water is just gross. Lots of oil. I dont understand where its even coming from. The motor seems to be running great though!

[@BoilerDan1]

That’s normal due to the higher level of oil to fuel mixture recommended during break-in. Once you change over to the 50:1 mix it will be totally clean. Special note: you don’t need to use a barrel or bucket. It was winter here, and I kept adding snow to keep the water cool. Run a hose to your barrel or take it out on the water!

[@greyagle]

Hey, Dan! I have had one of these for two years now with a lot of use including week long trips in the Everglades running the motor 4-5 hours a day, so I am pretty pleased with it. I have gotten a second one because I like having backups on the wilderness trips. The new one is only 30 minutes into break-in, and I can't keep it running for more than 3 minutes at a time (usually less than 30 seconds at a time. The tank and filters are new, and I tried loosening the cap on tank first time it quit. I notice tiny bubbles going up the return line to the gas tank when it's running. How normal is that? Any ideas here?

[@BoilerDan1]

I’m no real expert on that. Hopefully another viewer can respond. You could change or at least re-position the line that’s having the air bubbles in it. That sounds like a good place to start. Mine did something similar when it got hot. I thought it was a vacuum issue with the fuel cap? But you loosened that already. I’d start with the fuel line leaking bubbles? Sorry I didn’t have a specific answer.

[@alasdair4161]

That is most likely the fuel pump in the carburettor. It is a diaphragm that works from pressure pulses and may simply have loose screws (plates valves and diaphragm are all sandwiched together) Just try loosening then re tightening the screws in a cross pattern, if its still bad, replacement carb is the next best option. They are cheap, but again worth checking the screws are all tight befor use. Good luck.

It’ll keep the cost down if you can get one reasonable. My concern is reliability! The clutch wears out pretty quickly. It’s easy to work on but I wouldn’t get to far from shore! It’s the little things, fuel lines, spark plug. But if you change those items and keep an eye on things, the motor itself seems solid.

I just purchased a new one and no water is pumping. Nothing coming out . I don’t know what to do? Please any advice

[@BoilerDan1]

Water will only come out when the propeller is turning, at mid to full throttle. The pumping system is very simple. There is a paddle wheel down by the propeller that turns with the shaft. You can also check and make sure that nothing is blocking the water tube. I will put a link to one of my videos that might show some of the areas, although I don’t have one specifically on the water pump. There’s a little bit about it starting at about the 8 minute 30 second mark of the links video. kzbin.info/www/bejne/h6acgJ2Ol7KoqqMsi=Bn7lEPY682AukUdu

[@BoilerDan1]

Let me add that you should check the plastic port where the water should flow out and make sure it’s not plugged. But I think if you run the motor full speed, the water will come out.

[@HigherSelph]

Did you find that the water from the cooling system comes out of the whole bottom of the motor, rather than just its dedicated exit (sry, dont know what thats called)? Thats what mines seems to be doing, although it appears to be running just fine.

Yes, mine did do that. It’s not a problem. The water is actually backing up from where it exits. No worry,but I also was concerned. It’s a little annoying though.

Thank you for the video BoilerDan. I purchased a brand new one last year and only started setting it up now and cannot get the propeller to turn when i rev the engine. I have filled the gear box, checked that the shear pin behind the propellor is not broken and still cannot get the propeller to turn. Do you have any advice on this. I have dropped the whole bottom to ensure that the drive shaft is connected and it seems to be all fine. As an FYI I did check the water pump seal as well and that is appropriately positioned, but no water pumping which i assume is the fact that the propeller shaft is not turning - Do you have any idea what I should look at next?

[@BoilerDan1]

Next: Two items to try. 1st, the clutch spring is really not designed for a boat motor, it more for a weed wacker .... seriously it’s way too strong. So here’s your two things to try. The two bolts that hold the clutch on could be too tight, not allowing the clutch pads to swing outward which then turns the shaft for both the water wheel pump and the propeller. Second and you might as well do this step regardless. Replace the clutch spring with a lighter spring. I picked one up at a Menards store but any hardware store will work. You may have to get one that has closed ends, but you can bend or clip off the ends. I made a series on replacing the clutch, I’ll paste links below. kzbin.info/www/bejne/fWXUfapnadGZb80 that shows the spring. If I mentioned one that I ordered from Home Depot it turned out to be too small. kzbin.info/www/bejne/fmXQgXqrerChgas This one is putting it back together: kzbin.info/www/bejne/h6acgJ2Ol7KoqqM.

Hi Dan all your videos are amazing! Quick question for you, I got a hangkai 3.6 two stroke, the thing is, I follow all your recommendations about changing spark plug, gear oil and mix ratio gas/oil. everything was going really perfect in the break in process.... Until just right now. I am on my hour 8 of breaking this motor and then I decided to leave it alone for a moment while it was breaking. What happens next is that an attachment of my garden house ( one that it was bringing fresh water to the tank where I was breaking the motor) get loose and get stuck in the propeller, stopping it with the motor running. How long it was like that, I am not really sure, but I don't think it was too long, because I had one of my house cameras pointing to the motor, that's why I realized something was going wrong. To make the story short,( is already long, I know..) I went outside to check the motor and it was smoking more than normal, I stopped it immediately and I started pouring fresh water over the shaft, one that it was hot but not more than probably water boiling point, also the low exterior area ( the base)of the motor was really hot, like a clothes iron, so, I poured water there too. After all of this and thinking that I was probably done with the motor, this started again, everything looks normal ( I checked inside the motor before starting it again, fuel lines,wires, connections etc) even the cooling water was coming out normal. My question, do you think something that I couldn't reach to check maybe it could be fried or almost fried? Please get me your advice! Thanks!

[@BoilerDan1]

YIKES! I’m surprised that the sheer pin didn’t snap? It would have been a good thing as then the hose wouldn’t keep wrapping around. Someone else said that the motor is also air cooled. It sounds like you’re very fortunate that it’s still running. I think you’ll just have to keep going! I don’t think I’d worry about doing anymore breaking in. Just take it out and see how it does. Maybe slowly reduce the oil to fuel mixture? I still am thinking that your sheer pin may have sheered off? It is supposed to do that if the propeller stops from hitting something. I think you should check that out.

[@THELIFEDREAMER.1329]

@@BoilerDan1 Hi Dan, thanks for answering right away, I really appreciate that! Well, the water hose never wraps around the propeller, what happened was that a hose attachment get loose and got stocked between the propeller and the metal thing over it, totally stopping the propeller but the motor continues running ( hey Dan , that's almost funny yeah!) After that, and of course, checking all that it was possible, I started the motor again ( to be honest, I wasn't expecting it to start again) but, believe or not it started! Actually I continue breaking the motor after that, I just stopped the motor two minutes ago and looks like it is fine ( I hope so!) But, you are probably right, maybe the shear pin is broken or close to get broken. After the motor cool down I am going to check everything ,prop,pin ,fuel line , wires and all that is possible to check. Trust me I am very, very surprised and please with this motor. I was checking some reviews of this motor online and there is a guy that looks like know about these things, and he said that the design of this motor is really good, the problem is not the design of the motor, he said the problem is the really poor assembling process , and the lacking of quality check in the factories. I don't really know how much of true is on that affirmation, but, well I kind of tested it ( by mistake by the way) whatever, I really start to feel very pleased with this motor even though that when I decided to buy it, I said to myself, whatever it happens it is going to be a learning experience ( I am trying to learn more about outboards, I love going on the water but I realized that to do it safely I need to learn more) Dan, one more time, thanks for answering and giving me your advice about this, I deeply appreciate it, and I am planning to do exactly as you told me, thanks!

Was going from 30:1 to the 50:1 fuel/oil ratio a manufacturer recommendation?

Yes, info from Hangkai: (see link below) The 30:1 mix is for breaking in the motor. It will produce an oil residue out the exhaust. Once you go to 50 :1 it is much cleaner running. NOTE: on their web site you will see they show the mix of 25:1 for break in period. I didn't do that, and would guess that would even create even more oil residue and possibly foul the spark plug?

Actually it’s near impossible to get ethanol free gas anymore. So I bought the highest grade of fuel but you can also buy an additive that helps. Any Walmart type store.

The bolts holding the clutch need to be tight, but not so tight that the clutch can't swing out to turn the propeller shaft.

I purchased through eBay as the price was less. The advantage of the 4 stroke is you do not mix oil and gas. It also is air cooled. I choose the 2 stroke because I have to lay the motor on its side to transport it. With the oil and gas mixed, there is less risk of spilling and I have heard that laying the 4 stroke on its side can result in oil causing some problem. But the choice is yours to make. Maybe research some more on the differences will help you decide.

Questions: With the lack of availability of non-ethanolated fuels any more, what do yo do? As I run older Merc motors, I was advised to use add an additive such as Stabil 360 for the ethanol. Also, all I've seen are 3.5/3.6 hp motors. Are there bigger motors, like a 5 - 6 - 7.5 hp, available? Need a larger motor for the type of water that I hit & size of boat I have... thanks

The company does make larger motors. One of my video's shows how to access their web site and it will show several motors. But I didn't purchase through them directly.

I cover that topic in later videos.

[@BoilerDan1]

One additional comment: I want to clarify the break-in. Yes, do very the speed, but not full out top speed. That puts a lot of stress on everything, and you want it to get everything moving smooth before putting stress on it (My opinion). Even after the break in period, mine would sometimes kind of jump or kick/lurch and I think it was due to it needed more run time? But it might have been due to the vent in the gas cap not opening up when it needed too? Anyway, now that I have run it several times, it runs smooth.

So a viewer recommended NGK spark plug. I did that and have not had any problem with that sense then. I had a fuel line rot out. I had the cut out switch wire slip off its connecting terminal.

It is a bit loud.... It's kind of like a weed wacker with a propellar instead of string. The exhaust port is under water so that deadends some of the noise. I tried to put some sound deadning pad inside the housing but it really hasn't helped much. As far as storing in an aparment goes... It is light weight. Being two cycle, there is no oil left inside it to spill. You can simply unscrew the tank from the motor then pour out the fuel, so there wouldn't be any gas/oil mix inside it. But you also might need to work on it sometimes....Ie... fuel line replacement, starter cord replacement. Nothing that hard so far for me. A sturdy table outside (picknic table?) or even the ground I supose. I would also make sure you buy a new one.

[@BoilerDan1]

Not to worry. If I understand you correctly, the top of the vent post could mean that there’s something blocking the bottom holes that it usually comes out of. There is a single screw holding it on. You can remove it and make sure the pathway is clear. Regarding some water coming out on the two sides of the engine cover is probably from the rubber waterlines at the place the connect to go into and out of the motor. It has two pinch type clamps that are pretty cheap. You could replace them with a better clamp that screws tight. But that water is harmless. But a little annoying.

During break in, the fuel oil mixture is a little rich on oil and thus the smoke. If you’ve gotten a few hours on it, maybe a mix of 40:1 ?.... once you are done with breaking it in, the 50:1 mix will run clean with no smoke or oily residue. I’ll check out your video sometime this morning. 👍👍

[@BoilerDan1]

IMPORTANT: I’m starting to watch yours and realized that.... I broke mine in , in the winter and kept adding snow to keep the water cool. Run a hose in your bucket so you don’t over heat it. You can also break it in while using it 👍

[@ramonfolgar5539]

Hello Dan, I bought a hangkai 3.6 again and I have concerns about a v Ed or that the motor when it is not walking does not pump water as well and the other thing that I appreciate is that you have to accelerate a lot so that the block Ed works you have any suggestions or solutions possible for these two things thanks

[@BoilerDan1]

Ramon Folgar : at an idle it won’t circulate water. The water pump is hooked to the shaft the rotates the propeller. I had to replace the clutch in mine. At that time I put a much less tight a spring that disengages the clutch. I highly recommend considering doing that. Here’s a link showing that video of the spring. kzbin.info/www/bejne/fWXUfapnadGZb80

[@ramonfolgar5539]

@@BoilerDan1 Good morning Dan, do you think that changing the cloche spring could solve the problem or have to be replaced completely, nothing happens to the engine when it is on without clogging or apart from the water it has another type of cooling for when it is in that been, thank you very much for your attention and time regards Ramon

[@BoilerDan1]

When idle speed it will air cool, but you shouldn't let it idle for long periods of time. If you have run it for a season and notice you must run it fast to get any water to flow out your clutch is wearing out. So yes, you probably need a new clutch. I replaced the spring in my new clutch and it works much better. Water comes out with just a little acceleration. You can find a weaker spring at hardware stores as the one that comes with a new clutch is still to strong. I found my new clutch at Amazon, here is a link: www.amazon.com/gp/product/B07J6F4J6M/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 And I made two video's showing removal and replacement. You should be able to find those on KZbin.

[@BoilerDan1]

@@ramonfolgar5539 I'm not sure my earlier reply was clear. It does sound like your clutch is worn out. So I think you will need to replace the clutch and while doing that, also replace the spring that comes with it. The spring is much to strong for this little motor. I hope that is clearer than what I wrote earlier. I was happy to try to help.

Which is the best OBM for sea use? And for Intex mariner 4 boat.

[@BoilerDan1]

I'm in middle America, no ocean for hundreds of miles. The 3.6 hp Hangkai doesn't have a lot of power, so I'm not sure it would be my choice for sea use. You might check KZbin for users that have it in salt water, or make sure you rinse any salt water out of the unit after each use.

How do I change the oi? Is there any oil drain? Please help, I am breaking it (10hours are up) and it's time to change the oil.

I’m assuming that you have the 4 stroke motor? Mine is a two stroke where I mix the oil with the fuel. That being said, I can still help 😁. On many small engines like this, there isn’t a separate drain plug. You remove the one where you added the oil to start with and then tip the motor and drain it out that same opening, problem solved!

Hi mr dan..my hangkai 3.6hp not flowing water thru the exzos..only smoke..and my field test my engine running wheezing..why this thing happend..

[@BoilerDan1]

I can’t know for sure. Water will only come out when you accelerate enough that the propeller is turning. If the propeller isn’t turning, you might need a new clutch. The water pump is just a simple paddle wheel that attached to the shaft near the propeller. If the paddle fins have broken off, you just need to replace the water pump wheel.

Tks Captain John

[@BoilerDan1]

Capt. J. You are in a warmer climate than me, so be sure to run water in the container so you don't overheat the motor. I'd give it a cool down every couple of hours for sure. Also don't run at one speed, I set a timer and changed the speed a little about every 10-15 minutes. You also have to get enough speed to engage the propeller or you won't have water pump through the motor. Idle speed for a couple of minutes is ok, just not a long time. Some people have had trouble getting the propeller to turn. One checked the clutch system and said it was to tight.... Another said take the spring off, and the clutch will last a lot longer. I'm considering making a video of how to get to the clutch.... It would be a good winter project..... Regarding the clutch system; You need to rev up to get it turning, then back it down a little to the speed your using for break-in. Also The fuel cap vent hole doesn't work real well, so you might need to loosen it a bit as you run longer. I'm not able to provide information regarding the valves. I've not opened the motor up, and that is a little beyond my experience. You can also break the motor in on the river, just no full speed until you get the break in done, and then I'd take it a little easy at first.... But mine is holding up fine other than the things I listed in the videos. CHANGE THE SPARK PLUG! The ones in them are junk.... Anyway, enjoy the adventure. Thanks for watching.

Hangkai 3.6 hp Gear Lubricant Change kzbin.info/www/bejne/il6vZqKajMmoq80 Note: At some point I noticed a fill line inside the housing. Just be sure not to overfill. There needs to be air space inside to allow for heat expansion. Otherwise you will get water vapor sucked in when it cools. If you don’t want to watch the video, I ended up using SAE 90 GEAR OIL.

[@NoahBailie]

what would happen if you dont break it in?

[@BoilerDan1]

I'm not an expert on that issue. You could use it during break in, just vary your speed and don't go full speed. So the break in doesn't require being done on land in a bucket. For example you could take it out and run it a various speeds maybe for 10-15 minutes at one speed then go up or down slightly. The important thing would be the fuel to oil mix at 35:1 for at least 10 hours of operation. Then you can work up to the 50:1 mix

[@richardtominaga8957]

You break it...

[@jaybrowning2225]

So after break in I can go to 50-1 ??

[@BoilerDan1]

Yes, after breaking in the motor, change the mix to 50/1. It will burn cleaner. Also it’s better to break the motor in out on the lake, not in a bucket or barrel. You must keep cool water running if in a barrel. I kept adding snow as it was winter when I got it..😂👍

[@stevencartlidge6574]

Hi, I have the same motor. I have a question. My motor will run just fine for about 10 minutes. Then starts cutting out. I found that if I fiddle around with the choke I can keep it from going dead.

Because when running right it pushes my 10' flat bottom boat just fine at 5mph.

[@BoilerDan1]

Steven, I’m not a mechanic but I will share some things that either I have discovered or someone else has suggested. More than one person (including me) discovered that a vacuum develops in the fuel tank. Then fuel can’t flow properly and it can even stall the motor. There’s a relief tube inside the fuel cap. If you remove the cap and look you’ll see it. Kind of like a pinched tube. There’s a little hole on the top of the cap. I poked the backside of a similar sized drill bit (or wire) through trying to stretch it out a little. Also loosening the fuel cap will work too. Only other thing I can think of is a clogged fuel filter but I doubt if that is it. Especially if it starts out fine and then after running for a while..... it’s gotta be the vacuum.... to test just loosen the gas cap 😁. Let me know if that works...Others will appreciate your feedback too!

What's the best oil for the full mix

[@BoilerDan1]

According to the manufacturer, after you break in the motor at a 35:1 fuel / oil ratio, it is recommended to move to the 50:1 fuel / oil ratio. That will result in a cleaner burn as it has less oil. I just recently finished the 10 hour break in run and ran my first tank close to 50:1 and it does run much cleaner. little to no oil residue coming out of the exhaust. That is also better for the ecology of the planet :0) When I take it out for it's first real on the water run, I will probably run it with about a 45:1 mix just to work towards that cleaner 50:1 mix. Hope that is all clear?

[@aaronbishop3754]

Can I break it in on the water?

[@BoilerDan1]

Yes, that’s actually the way it should be done. I got mine in January 🥶. Couldn’t go out on the ice 😂

[@FishFactsTV]

So when I opened mine up it had gear oil in it, so I closed it back up. The engine ran but the prop wouldn’t turn. Opened the lower unit back up and there were metal flecks, I replaced all the oil and fired it up again. Still nothing. Any ideas?

[@BoilerDan1]

If you have the water cooled motor, it works on a clutch system. So at idle the prop won't turn. However the metal fragments are a little concerning..... If nothing is wrong with the unit, then if you accelerate the motor about half way, you should get it to turn. It may take a little more than half way to full throttle and it takes a couple of seconds for it to get going. You can kind of hear it kind of slip into action so to speak. A bit of caution though, I have heard of people having the springs in the clutch slip off, but that clutch is not near the propeller. Did you purchase it new? It usually ships with no fluids in it at all.... If you got it used, I'm going to guess that the clutch system is defective. Search some more on KZbin and I think you can find something on it. Even if non-English, the video will show you the area it is in.

[@FishFactsTV]

BoilerDan1 it was definitely new. Maybe they changed their shipping practices. It seems like there is something wrong with the lower unit. I am gonna try to open it up again and see how it looks after running it again, but I may just abandon it and buy the Yamaha. It seems like it’s not turning at all even when I crank it up.

I purchased the hangkai 3.6 motor and received it. When I opened the box everything was there and no damage visible so I proceeded to follow instructions step by step on setting motor up to be started. I put gear oil in shaft compartment and closed it up. I used a barrel of water mounted motor on it and proceeded step by step to start it. The fired on the first pull and idled perfectly I was impressed but when I advanced the throttle to start prop rotation it would not turn at all so I idled back down and shut the motor off think there was something I didn’t do but when l grabbed prop to turn it it would not turn freely at all in fact it seemed to be in a bind so I took prop back off to see if there was something in the gear housing but I didn’t see anything wrong. I put it back together and started it again ant started immediately but when I tried to advance the throttle the prop still wouldn’t turn ( very frustrating). Has anyone had this problem on this particular motor before? HELP !

[@BoilerDan1]

1st and most important: When I used a bucket it was very cold and winter. You must supply constant cool water or you will overheat your motor....you can do it on a lake or pond too. Ok, that being said: The propeller works via a centrifugal force clutch. You can try to fully accelerate the motor to get it started turning, then back off a little but make sure you are getting water flowing out of the cooling port. The problem with the motor is the clutch has a spring that is too tight for this application. I will put two links at the end showing the clutch. I ended up replacing the spring with one from a local hardware store. It is much lighter and pull open easily now and has worked much better. I did have to pry open the ends of the new spring to adapt it to this use but it works well now. I'll also suggest that you order a replacement clutch so you have it on hand. You can search Amazon for "Clutch Drive For Honda GX31 GX35 and you will get several to chose from. That clutch is the same that came with your motor. Let me know if I can help more and I will try. Here are links showing how to replace the clutch...and a little more follow-up on the topic. kzbin.info/www/bejne/fmXQgXqrerChgas kzbin.info/www/bejne/h6acgJ2Ol7KoqqM kzbin.info/www/bejne/fWXUfapnadGZb80 kzbin.info/www/bejne/gpXXeod8rZuBY7M

[@BoilerDan1]

One other thing that I’ve discovered.... there is a line to fill the gear lubricant up to. It’s just about 1/2 below the top. There needs to be a little air in the compartment to allow for expansion when the gear lubricant gets warmer and expands. I’ve learned quite a bit in my adventure 😁

[@dsmith6943]

The shaft feels like it’s bound up from the start the motor only ran for maybe 60 seconds tops. Shouldn’t you be able to turn prop with your hand easily when the motor is not running? I can’t turn the prop at all with my hands that doesn’t seem right you can turn big boat props with your hand even if it’s in gear I just don’t know what to do would you send it back sir ?

[@BoilerDan1]

Because it doesn't function like a traditional motor, the gearing is never in neutral and so the prop won't turn easily. I wouldn't force it either as you might bend or break of the gears. If you have the option of returning it, you could give that a try. If that doesn't work out, watch the disassembly video I sent you and consider taking it apart to that level and check out the clutch. I've heard that some have had the two bolts holding the clutch in place were put on too tight and the clutch can't spring open. You could also remove the spring during break-in. That way, it would take very little throttle to engage the prop. The down side is that in actual use, you could never be in idle, the prop would always spin a little. If you watch the video, you will see how the spring works, and putting in a lighter one would be best. But again, if your more comfortable returning it, or if you could return it for another one...That's a good option. But with this motor, I've done a lot of tweaking. I enjoy doing that... But I can understand your hesitation. Let me and others reading this know how it turns out. Any input may help others decide if they want to consider buying one! If you still have questions, I'm happy to try to assist. But realize, I'm not an expert, nor anywhere near a mechanic. I'm just retired and wanted to explore a little with the motor and raft. I didn't mind the risk... Best wishes for your journey too. Maybe contact the seller for their view. But I'm guessing loosening and retightening the two bolts that secure the clutch would be a good start... I'd replace the spring at the same time. But that's me.

[@yahiakelaiaia2392]

[@BoilerDan1]

The motor is somewhat cooled by water. But it’s a very simplistic plastic wheel down near the propeller. It does push through some water and I suspect it’s air cooled also.

We sound a lot alike, I didn't need it either, just bought it to play around with! First thing you need to have on hand for future use: Clutch replacement: Here's a sample, but you can enter the info about HONDA GX31 GX35 GX35NT Fit MITSUBISHI TL33 TL43 TL52 T180 T200 T240 Bush Cutter Tiller Trimmer Strimmer as that is what fits. www.amazon.com/gp/product/B07J6F4J6M/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 If you watch all my video's, I recommend replacing the clutch spring with a lighter weight one as it will improve it working and lasting longer. Fuel lines. I'd keep the ones on it for the first season then replace them. It's the ethanol fuel that eats them up. I think they are now making ethanol friendly fuel lines.... Break-in: Actually you can break it in while using. Just very your speed every 5 minutes or so. The way I did it isn't the best, I just don't have water around me and I purchased mine in the winter. You need to keep cooling water running if you do it in a barrel or bucket and I didn't point that out in my videos.... I was pouring snow in the bucket constantly.... Don't want to get it overheated...although I've since been told that it's as much air cooled as water cooled... If I had it to do over again, I'd consider the air cooled 4 stroke model....In hopes it would be quieter? The gear oil can be the full synthetic kind for the best protection, I think the manual says 90 weight. Here's a link to the manufacturers web site: Look under the tab for "Articles" and you will find a lot of information and trouble shooting stuff: www.hang-kai.com/en/nr.jsp I tried to copy the link to that page? The pull starter is another issue that you will want to have on hand. Mine came with two. If you remove than handle and the string gets pulled in to the winder it's a goner! No way I could figure out how to get the spring re-tightened. The rope will wear out too. Coating with bee wax will lengthen its life. You can order those too: eBay: www.ebay.com/itm/324402571624?hash=item4b87e66968:g:dUYAAOSw~~RfyFDn You can also find the little carburetor, just do some searching... They are pretty much all the same little gizmo. Hope that helps? I don't know much about modifying the motor, but it's easy to work on! Aluminum, so don't overtighten the bolts and screws! But the block itself seems very solid! It's the little things that are cheap! But I have had a lot of fun with it... But it's a noisy little bugger, not great for trolling...But it'll get you to the other side of the pond.... It'll be better on a solid small craft....My little raft was too spongy, causing me to lose some thrust and power. Enjoy your adventure! Thanks for watching 👍

My boat is not a rubber boat. It is V type's sleek boat and only 25 kilograms go. I am 73 kilograms. When I alone in the boat and run the fastest on the hangkai 4 stroke 3.6hp I get 8 kilometers per hour. I think it's too slow I want to know is this normal?

[@BoilerDan1]

Both the 4 stoke and 2 stroke are not speed motors for sure. Kind of like a trolling motor with out batteries. :0)

[@BoilerDan1]

That is normal for these small motors.

[@Rattlerjake1]

They are not designed to water ski behind (LOL), they are made for use in ponds and small lakes.

Hi Dan, been watching your videos and really appreciate them. I have a question and was wondering if i could shoot you a picture of the o ring on prop...not sure if it looks right and want your opinion..can i email you?

[@BoilerDan1]

Sure, but I'm not sure if I will know anything. Mine has leaked a little water inside almost every time! I'd replace the o ring. copy your email to me here on this thread, and I'll email you back from that. Thanks

@@BoilerDan1 [e-mail]....we noticed a little piece of "metal" stuck to the side, inside the oring...just looks out of place
