For me is cleaning a carburetor the easiest job to do when I service my outboard, i am 14 years old and I learned from you guys and i want to thank you for that!

[@smannee]

Keep wrenching brother.

[@kaidenmarthaler6017]

Same for me. 14 year old and love working in outboards

[@ivanstefancic3151]

Well done mate!

[@smacktalk2753]

Keep it up, the best way to learn your boat from top to bottom is do as much as you can yourself. When you have to ask for help, help them and absorb everything.

[@jurridoras4001]

Goed bezig ruben!

[@r8drvr819]

It's a pleasure watching you work! I am not a gear head, so I enjoy those who are mechanically accomplished!

[@DJSbm-28]

Ah the little motor that could. These small motors seem so much easier to mess with. Thou the carbs always gave me fits. Seems like I most always would miss something. Thanks Arron enjoy that boat, looks fun. Stay safe out there! 😎👍🌴

[@c.shoefish]

I have a Yamaha 25 2 stroke and synced the carbs up earlier this year and man, what a difference it made!

[@garycooper3021]

Your videos are EXCELLENT! Informative, understandable, educational. Keep doing them.

[@BornAgainBoating]

thanks man!

[@Captain_kinz]

Also the California brass plug that you have to drill out sometimes to get to the flat head scrw sometimes that gets all clogged up in there.

[@thediplomasta5891]

This is my everyday life; Little motors. Powertune, ring-free, and seafoam are all the same stuff, so buy which ever one is cheapest for you. 😉 Those little auto start valves are really strange. According to yamaha, they have a wax inside them that slowly melts when voltage applied, which allows it to slowly move somehow. I dunno, I've never cut one open.

[@apackwestbound5946]

The "best" make it look easy. You are the best-thanks.

[@BornAgainBoating]

You are welcome!

[@apackwestbound5946]

True statement!

[@saltydogsusa6382]

Would love to see a video on fuel tank anti-siphon valve and why it's so hard to get gasoline out of a boats tank. After Ida we had really bad gas shortages and with 175 gallons in my Contender I was looking for a way to get some gas out of it easily. Alas, that didn't happen. Thanks for all the great vids you produce.

[@thediplomasta5891]

Sometimes, the end of the pickup tube inside the tank can get plugged or blocked. I've seen it a few times, always a different reason, but the same cause. The spring on the anti-syphon valve is very soft. If it isn't gummed up, it should easily release. If you remove the A.S. valve, you can poke the little ball in the back of it and feel the spring tension.

[@2wayzplayz179]

Wow I did not see that merch plug coming that was a silky smooth transition. Couldn’t have been better.

[@UltraMagaFan]

Our motor would be extremely hard to start, shut off when we gave it gas like that 40 horse Yamaha, there was gas leaking everywhere, and it would constantly foul plugs so badly we had to replace them. We rebuilt the carburetors and it fixed all of those problems. It was very easy to do too. Carburetors are not that complicated.

[@reelcs]

Ah .. tinkering with these small engines after working on large one most of time is lots of fun!

[@Emolswift]

Can you do a guide on how to adjust the mixture screws on the carbs after a rebuild?

[@flywelder]

Another great instructorial video! Thank you ❤️ didn't see you place a scree driver to any screws, what screw would I be adjusting to get the carbs in sync? Must be more than the idol screw s?

[@Fireship1]

Now install a water separating fuel filter to protect all that work!

[@jimmymiata7855]

Did your shop supply the sync tool for u or did u end up buying your own? I love that thing

[@OfficerDave78]

Professional mechanic right there !

[@SINIS0RSA]

Until what year Yamaha's F40 had carbs?

[@mahimahiaddictioncesargonz5445]

What's Good Aroon Mahimahiaddiction Team here 🎣🎣💯😎🦈🙏🏻

[@marcwetter1192]

What is that thing called were u can measure the flowing air with

[@pete926]

Any carb that needs cleaning get "ultra-sonic cleaning"! That's how I fly.

[@vinhoi69]

Please Help. I have an 1989 Johnson 70HP rebuild by Coastline Marine in Florida. The rebuild cost $3180. (rebuild include: bore the 2 bottom cylinders to the next larger size piston. replace the top piston for cylinder 1, rebuild carbs, new thermostat). The guy told me to check the ignition and timing by a mechanic. I have called every marina in Boston area to have them check the timing for me but no one is willing to work on older motor so I have to check the ignition/timing myself. I have watched KZbin videos bought 2 manuals to do the timing/ignition myself. When I check the TDC of the motor, new TDC mark that I've found is 2.5" to the left of the factory TDC. Is this correct ? TDC needs to be correct before I can continue forward. Thanks for your help.

[@DIY_Z]

What could the problem be if it is direct injected?

[@ESPPsycho]

Thanks man. Any chance you have a video about a cold 2-stroke cutting out at idle in neutral? Makes shifting on my way out of the marina fun. I basically always have to give it a little gas. Short of too low idle adjustment, I figured low compression might do it..

[@thediplomasta5891]

Could be several things. Start with the basics, which. Are spark, compression, and gear oil status. One of those things will usually lead you to the issue, along the way of checking them.

[@DirtMcGert29054]

I agree on a BF40 pull them off as one big peice

[@malekodesouza7255]

Reminds me of synchronizing my old VWs with dual carb setups.

[@firedude4080]

What would you say about the direct injected motors and having a sheen on the water...? Where do I start looking to find the cause of the fuel leak

[@heldercorreia9350]

Vapor separator tank (Optimax)

[@UnderwaterHunter96]

I have the exact same motor on my KeyWest skiff

[@johnbumpus7138]

So when using that tool on a V6 outboard can you sync it one bank of carburetors at a time?

[@dobbysound]

thanks for your help from GREECE

[@BornAgainBoating]

Happy to help!

[@Daandeslions]

0:37 The short shafts were sold out I guess?

[@DirtMcGert29054]

Those carb Honda’s always have cracked tubes in the carbs

[@UrbanFisherman]

🔥 info bro 👍🏾

[@lukeluke3199]

Can anyone thoroughly explain the link and sync process on a Yamaha F150?

[@neillee3793]

Got a Yamaha 9.9 hp with electric ignition at the aft steering station that fails to shut off with ignition switch. Disconnected kill switch lanyard and replaced ingition swith - still will not shut off propertly, have to engage electric choke to kill motor - frustrating!

[@neillee3793]

Suggestions?

[@Grady252]

I wish someone would show how to do the sync and link on a 200HPDI.

[@karlojuratic]

What tool is this at 3:51

[@smacktalk2753]

Lobster boat. Nice

[@goncalometelo7002]

According Yamaha these F30/F40 are the most complicated carbs they have because of the tiny passages and acelerator pump. Sometimes these carbs to be properly cleaned need to be drilled. From my experiance this carbs sometimes are a pain to clean but the most dificult I had to sync was the 1st generation of F50 (up to 2000). Now days most people hate 4 strokes with carbs but no complains here, I still have a F100 and a F60 with carbs free os problems because I use a good pre-fuel filter and dont let carbs settle with gas for a long time.Thanks for another great video. Best regards from Portugal

[@jimmymiata7855]

Sync and link them carbs bro 🤙🏼

[@PFLEONARDI0906]

So the moral of the story: having clean fuel and fuel filters to begin with is 60% of the carb operating properly…the rest(floats, enrichner, settings, etc.) is normal wear/maintainence….

[@malekodesouza7255]

And drain your carb bowls if the boat is gonna sit for a while.

[@thediplomasta5891]

The other 40% is using only ethanol free gas. People just don't understand how much of a difference it makes in the engine maintenance, down the line. It's also the reason that they could use steel gas tanks, back in the day. White gas=no rust in the gas tank (or water).

[@growlith6969]

Not saying "stick to fixing boats" but you had a few videos that came off weird and seemed to be hunting for purpose. This one is back to those good ole feels. Hope you throw all kinds of stuff out there, but, have a goal for the video when you go to flesh it out. Drop a line if you ever wind up in Savannah, we have plenty of content to film up here and I will even hold the camera for ya ;-)

[@smannee]

I love any excuse to work on my 15h hp 2 stroke yamaha. Such a fun engine.

[@UltraMagaFan]

You must not keep that thing on a boat. Working on your motor is the last thing you want to do. Most people want it to be as reliable as it can.

[@smannee]

@@UltraMagaFan to the contrary. It is bolted on to my tender. It's extremely reliable and has been since I bought it. My son uses it as a run about when its not on tender duty. The work I was referring to included regular servicing, impeller changes, cleaning my carburetor and replacing anything that doesn't work properly or that has surpassed its service life. I am not an outboard technician (physician by trade) but I'm fascinated with machines and making my outboards work as perfectly as is possible. One love from the Southern Caribbean (grenadines)

[@UltraMagaFan]

@@smannee Well in that case good for you. I’d imagine you guys down in the Southern Caribbean use boats a lot. If you have the time you could go to a technical college learn how to work on outboards become a technician and make extra money off of it in your down time. It wouldn’t even be working since you enjoy it. I don’t particularly enjoy working on outboards (especially when there’s small parts) but that’s what I plan to do. The only job I want pays $35,000 a year. It’s a great source of money where I’m from. Especially if you also know how to work on jet skis engines and inboards.

[@smannee]

@@UltraMagaFan thank you for the advice and support. I don't think I will become a certified tech. I am Doctor, that's what I meant by physician. I make a pretty good living. I do spend a lot of free time at my friends garage/shop and I get to hang out with some amazing technicians and machinists. So I guess I'm a frustrated engineer. Hahaha.

[@UltraMagaFan]

@@smannee I know what a physician is lol. Even if you make a lot of money it’s still worth it to get paid to do something you enjoy in my opinion. Especially if you enjoy what you do.

[@zacpearson1878]

Isn’t it easier to just buy a new carb for it rather than disassembling

[@thediplomasta5891]

🤣 Sure! Anything is easier, if you have money. A new carb is around $500 each. There's 3 of them. Go nuts.

[@zacpearson1878]

@@thediplomasta5891 depends on the motor itself but even my boat guy that has been in the business for 30 years doesn’t rebuild em budget yeah sure rebuild it but if you can it’ll be better if you can drop a new one in

[@thediplomasta5891]

@Zac Pearson I was talking about the motor in the video. But 2 stroke carbs are usually very simple and just need to be purged out. Except for the plastic ones. Eesh. Whose idea was that?

[@nobody46820]
