How to fix a submerged two-stroke outboard motor

In this video I show how to repair a 15HP Yamaha two stroke motor that had been on a boat that sunk. We go through cleaning up a submerged battery and then cleaning all the water out of the motor and getting it restarted. If your outboard motor has been underwater this is the video for you.

What I enjoy most about your videos are that they're not canned perfection. So you back track and re do, and rethink it, and make mistakes, and regret short cuts, and so you're just like the rest of us wrenching away. You gotta be part masochist to be a mechanic and your videos really help a novice know what they're getting into. Nothing like figuring it out finally though. Thanks for the hard work you put into your videos.

[@DangarMarine]

Thanks mate. I disagree that you need to be part masochist to be a mechanic, I'd say closer to 100%. ;)

[@555Trout]

oh man, that made me laugh mate. You're right!

[@dennisdavis8649]

When I first started watching your videos I thought you were just some hole in the wall mechanic. The way you were dressed threw me off. Now I know you are a professional boat mechanic

[@DangarMarine]

Technically a professional car mechanic, boats are just a part of living on an island. :)

[@Brendan77132]

Hi Stu, I just wanted to thank you for your videos which helped me no end. I managed to start my 2004 Mariner which had been sunk in salt water and was started once after sinking, but sadly seized solid and was left to be a parts engine as was the advice of all the main dealer marine mechanics in Ireland(almost, I haven't met all of them). Upon watching your videos I decided I would have a crack at fixing it, and low and behold it's running again. I having never posted a video before but I was so pleased I posted one of the engine 2mins after it started. Thanks a million Stu!

[@DangarMarine]

Hey Brenda. Good job on getting the Mariner to run again. It must have been very satisfying to hear it fire up after being left for dead. I hope it gives you lots of good service. :)

[@silveradolovinredneck7829]

How did you get it freed up? My evinrude is completely salt water seized and I refuse to believe it's not fixable... like everyone has said from the start... here we are almost one year later and I'm still set on fixing this motor!!! So any and all real help/knowledge on this (benefitial and progressive help) it would so greatly be appreciated.. I'm just ready to see it pull, fly wheel turnin and crank and fire already.. theres just mo way it's a lost engine or it's not fixable... even if theres broken seals or corroded parts, there is a way!!! I just dont know the way...

I discovered your series just a few days ago (in the usual way: just looking for stuff I'm interested in), and found your more recent videos. What I immediately liked was your on-camera persona-- well informed, organized and devoid of kooky bullshit (I think you know what I mean). Plus, you have an understated, dry humor I truly appreciate. Just now, watching this much older video, it struck me how far you've progressed from your early days of vlogging to the present. Your potential shows in this video, and it is proven in your later videos. Well done! I suppose better "homework" contributes to higher confidence and better delivery in the production. You're tops, mate! I'm American, but I'll steal that phrase shamelessly. Carry on, DangarStu, PLEASE! I find A LOT of videos I want to watch to see what they are doing (and how they do it), but I am repulsed by unnecessary antics and camera mugging and goofy antics which have no contribution to the info purportedly offered. Got no time for that. Carry on!

[@shaddec55]

Plus, I absolutely agree with the "coffee in the morning, beer in the afternoon" philosophy (but when it's blazing hot, water has its place...).

Man your vids are the best, just saved a 1968 evinrude 18 hp fastwin that my brother in law left in the boat and let the drain hole clog up and covered the motor with water. it purs like a kitten now!! Just picked up a 1957 same hp that is my next project!! Thanks for all the good advice and keep up the good work, thanks from Indiana USA!

Hi Glenn, glad to hear you got your Evinrude back up and running. The '57 sounds like a worthwhile project too. Good luck!

Complete respect, but how nice was it to see a pro around about struggle to get the blighter started, gives me, a complete armature confidence to stick with it and not get fazed. Thanks mate

[@mrsfireleg]

Nice vid. Back in the 60’s one of the factory tech manuals recommended not using high pressure air to blow out the carb. There was a possibility the high air force could distort the shape of the float if it was the hollow brass type. No problem with the cork floats. I used a bicycle pump or just blew by mouth after that.

[@DangarMarine]

She's always got something funny to say. :)

[@deansikorski6596]

Not sure if it would work on an outboard?, sometimes on small engines (brings and stratton) after the recoil starter is removed, they put a socket on a cordless drill on the flywheel nut and use drill to start. Saves the pulling :)

Very Good! I know the feeling of victory over a non start motor.

[@tarzanmukai808]

I just picked up an Evinrude 9.9 HP, outboard motor that got submerged when the dingy boat collided with a save and the right amount of wind. The motor overall looks clean and looks as if they had drained and dried it out and the flywheel turned a bit (half turn), so I am hoping it will start after I follow the videos you kindly put out and show us the steps. This is my first outboard motor and I bought it for $30 dollars, because the had no use for it anymore, wish me luck and will ask questions along the way and upload a video when I get it started. Keep up the Great Work and a BIG Thanks for sharing your knowledge and experience🏝🏄🏿 Aloha! from Hawaii

[@jharl2]

I don't know if you knew this from before but you might have. anyway before you start a motor with a starter it's a great idea to turn it by hand. In this video you had a perfect opportunity to do that I didn't see it. And that would have been when you had it apart. Anyway thanks for your videos.

[@jimwoods9551]

In this video, he turned the flywheel by hand and it was obviously not seized. It turned freely using the recoil cord to spin the motor, again no sign of seizure or broken rings. I’ve yet to see him put a foot wrong. It always surprises me to see you tube heroes starting potentially valuable barn find engines on a starter motor, as if the manufacturer’s reputation is any protection against corrosion and gummed rings. It’s nothing to whip off the head on an old engine, or even boroscope the plug holes.

Only thing that i ever replaced is 3 water pump impellers, gear case fluid change and a couple of sets of plugs in the 20 years i have had it.

I always kept a spray bottle filled with water and baking soda handy when working on batteries. I'd spray the whole battery down before touching it to kill any acid on it's surface. Also handy to flush your skin if you spill any on you...

The engine was sunk in fresh water for 1 wk and I have followed your instruction re lube in cylinders but wonder if I should Should I be trying to lube the crank case as well as the cylinder head. Alistair in Scotland

[@stevewelches1955]

Thank you for the reply. Easy to under stand now.

[@bsrktm1]

Remove the reed next time. 3 screws. Comes right out. No gasket to break. You can blow out the water trapped under there. Also, you are able to look at the bearings and crank. I normally spray some lube on the bearings too. Clean that idle jet. Its tiny and clogs easy. Check the timing. Easy to do a static check on it. If the idle timing is way advanced, it probably didnt idle correctly before it sunk

[@DangarMarine]

Thanks for the extra info. So far the motor is still running fine but a more thorough job would probably only make it last longer!

[@bsrktm1]

You got it running. That's the main thing. A weak point on those motors is the impeller. It will completely break apart without much warning. Replace it often. Also-at least here in the US- the 9.9hp is exactly the same motor.Only the reed stops are different.Open them to 15 spec- instant 15hp. Carb size and jetting dont change. Your vids are good. BSR

[@DangarMarine]

[@DangarMarine]

Yes, does sound like more carb cleaning. Unfortunately it doesn't take much for a new drop of water to come through and block one of the jets again.

[@searider9922]

Stu, seems you assembled the fuel pump's gasket backwards, no fuel was going inside the bowl when priming the bulb firm. Happened to me once and drove me nuts till discovered the issue when the fuel pump was removed for inspection for a second time..

Thanks for the great videos! I have low compression in both cylinders - about 75 psi.

[@waughthogwaugh3078]

Hi Dangar Marine. Enjoyed this video, as another viewer commented, frank and honest. I have a cheap knockoff of the exact same motor across the ditch. Here is the scenario: Where the engine block bolts to the leg, a palm-sized section of the cylinder block casting around the right rearmost bolt cracked open. I did not run the motor at all after that for a couple of years expecting I may damage it further. This weekend I opened it up. In the interim it had salted but that was easy to sort. What I found on closer inspection was that there is a cavity in the casting around that bolt that is not used for cooling, cannot be flushed and is exposed to salt water and exhaust fumes. I am going to glue the loose bit back in with JBweld. Should I seal this random void off altogether? had wondered about spraying fish oil (tectyl) in these odd spaces too. Would be keen on hearing your thoughts and those of anyone else who may have positive contributions to make thank you. Cheers, Grant.

[@DangarMarine]

+Waughthog Waugh Hi Grant, I'm not sure I can picture exactly the space you are talking about, but I presume it is the exhaust outlet if you say it is exposed to salt water and exhaust fumes. When you say "should I seal it off all together?" are you talking about blocking it some how? JBweld and the like are good products, but with a lot of heat and vibration they can fail eventually. I'd be inclined to glue the parts together directly then layer a bit more over the crack once the original gluing has set. I'm a big fan of fish oil as a spray in a marine environment, but if it is somewhere you can't re-oil and it is flushed with salt water from the exhaust it may not last that long. Sorry I can't be more helpful. Can you link to a picture somewhere? Stu

[@waughthogwaugh3078]

+Dangar Marine . Hi Stu Thanks for your response. Here is a link to 3 pics and an explanation of each: drive.google.com/folderview?id=0B1P1BUuck1q9VDg0b1R3S2FVLUk&usp=sharing

[@DangarMarine]

Right, I can see what you are saying now. I can't see any reason you couldn't fill that void to add extra strength, it really doesn't seem to have any purpose other than securing the powerhead to the leg. I hope your rebuilt goes well. It's always great to see old outboard given a new lease on life.

[@stevedave8360]

I strongly suggest that you invest in a small ultrasonic cleaner for cleaning your carburetors. It works SO much better than cans of carb cleaner and compressed air, and it will loosen up old fuel residue and corrosion. They really work!

[@DangarMarine]

Good to hear they work that well. I was never sure if they were a bit of a gimmick.

[@DangarMarine]

The trick is to start it as soon as you can after coming out of the water. Only need to flush it in fresh for a few minutes.

[@FrkaDrka]

@@DangarMarine, I've got some regular wd 40, wd 40 contact cleaner (wast dry), and can of WD40 white lithium grease and 2 stroke oil. Do I need anything else because there is no shop there so I need to prepare? Is it OK to spray the contact cleaner (it's for electronic parts mainly) in the cylinders and then some regular WD 40 and after a few pulls some 2 stroke oil?

[@DangarMarine]

Maybe some methylated spirits to soak the carbs in. Spraying in cylinders would be fine.

[@FrkaDrka]

@@DangarMarine I've managed to start the engine and it works fine now! I've let it work for half an hour to evaporate the rest of water if there was some... Thanke you a lot wor posting these clips on how to! You are awesome!

[@AhmedAdly11]

What about the power pack on the 40HP Yamaha? Is the box water proof?

[@swss12]

i feel the best thing you could do with a sunk outboard in SALT water is to drain any fluids in it and then submerge it in fresh water to get any residual salt out of everything. maybe do that twice.. then dry out, clean, relubricate to flush out anything leftover. good to go

[@allanmoulton3745]

Here in Canada we add methanol to our fuel regularly in winter, to prevent gas line freeze ups. With large changes in temperature we often get condensation in the fuel system.

[@oceanz4me]

Hey Stu have a quick question if you have the time. Gotta an old Merc 8.8 that whenever I give it full throttle it bogs down. goes just fine at a certain level of throttle but just on the top end it starts to bog. I've pulled the Carby down a few times and given it a good clean, but still does the same thing. Comp is great for it's age and it starts first pull every time. All the low hanging fruit has been tested. Its the motor to my Tender and has been for year's and this has always plagued me but I've never put too much time into it because of many other issues onboard the Yacht. Any advice would be awesome matey! It'd be nice to get some more neddy's to get back to shore and back! Cheers Matt

Can you do a video on what would be the steps when you turn a zodiak ,and a two stroke engine gets wet and dosent starts.?procedure or steps . Thank you , cool videos . "Tabucito" is my channel . Thanks !

[@DangarMarine]

I would imagine it is a pretty similar process to this video where it sinks completely or just gets a dunking.

[@googleplusisdead]

I know this is pretty old (viewing all your old videos... :) But do you recall if the battery was still good? I'd expect a battery submerged in salt water (which conducts electricity) to discharge completely, at the very least, possibly very fast, neither of which is generally good for lead acid batteries. No idea how/if salt in the electrolyte would affect things, but there are videos about using epson salt in place of sulfuric acid/distilled water to revive really dead batteries. Wouldn't count on it lasting, however. BTW, unless plates are not covered by electrolyte, "they say" you should charge FIRST, as the level will come up with charging and you don't want it overfilled, especially if it came out the cell vents. RichE

[@DangarMarine]

Most batteries that go under do die either from the current eating the metal away or salt water getting into the cells. They sometimes aren't completely dead but I always just replace them because as you say, they never last long.

[@robertb7362]

[@steveneddy9492]

[@johnhanna8050]

what about the screws broke inside the tightening of the engine I'm not talking about the so I can't fall off the boat

[@rambuseighty-eight8874]

If you use penetrating oils like WD-40, you'll find that they protect, displace moisture and water, lubricate, all with no damage to aluminum, wiring, etc. Perfect for this application. Also in cylinders.

[@JackPhillipsBraunton]

Our boat capsized on it mooring becuase of an idiot drove past and created a big wave and hit the side of the boat. We are going to take the outboard off but it has been in a lot of mud do you think with some work it will run again 25hp 2 stroke mariner

[@DangarMarine]

+lundyjack Sorry to hear about that, people to need to be responsible for the affect of their wash, and are in fact held accountable by law. Mud won't be a big problem, just wash it all out with fresh water then begin this process of getting the water out and getting it running again. The sooner you can get it running again the better. The damage only really begins once it is out of the water and in contact with oxygen again.

[@scottlaw2401]

I submerged my 6 hp outboard. I managed to get the oil & fuel cleaned out before restarting. I ran the engine up each day for a week with no issues. After not running it for a month, I could not get it to start. It turns over, but no sign of any ignition. I've watched your video for tips. Given the engine did run, is there any possibility of there still being some water in the carb? I've not when as far as stripping this down.

[@DangarMarine]

It could be a corrosion problem. Try taking apart all the bullet connectors to the coils etc and making sure they are clean inside.

[@scottlaw2401]

Thanks, sorry but I'm sure what they are. Electrical connectors termination points? The only thing I had thought of was there didn't appear to be any sign of fuel when turning the engine over with the spark plug removed. I also couldn't detect any fuel on the pump discharge. I did strip the pump down, and all looked OK.

[@scottlaw2401]

Given the engine was run up each day following the submersion, I'm confused why the engine might not be getting fuel. The last time the engine was run up, there was no cooling water from the tell-tell. I did not run it long having noticed this, and planned to try and back flush the tell-tell to check it was clear the next time I ran the engine up, but have since never managed to get it started again,

[@nameless4284]

Hey im from the united states and not familiar with "Metho" at least thats what i heard you say that you cleaned the fuel pump with. What is it?

[@DangarMarine]

Sorry, very Australian term. It is denatured alcohol and is great for getting water out as alcohol is water soluble and will therefore bring the water with it.

[@LdnDan87]

What's the best way to flush it with fresh water and get the sand out the motor

[@DangarMarine]

Generally if the motor isn't running when it sinks you won't get too much sand in the pistons and crank case. You can take the spark plugs out and keep flushing fresh water in through the carburettors if you suspect there is a fair amount of sand in there or your can just bite the bullet and disassemble the crank case.

It started up but it stalls at idle. I have to keep holding the throttle. Any suggestions?

[@DangarMarine]

Sounds like the jet need cleaning. Even if they were cleaned, it isn't hard for water to come through from another part of the fuel system and block them again very quickly.

[@yeahhboii9377]

my 2 stroke yamaha 200 hp vmax has submerged, i rinsed as well as i can and took it to the mechanic in which he told me it would not start. it has been a week since that has happened should i even bother working on it or salvage it out for parts and take the loss (no insurance) :(

[@DangarMarine]

If it isn't seized there is still some hope, but if it isn't running very soon after coming out of the water the bearing will probably fail if not replaced.

Hi mate, i have an 86 johnson 15hp that is running reasonably well but can occasionally be quite temperamental (like its starving for fuel or air). iv noticed the cam roller is a dodged up back yard unit. is there a chance that is causing the problem?

[@DangarMarine]

Sorry, I missed this comment. It could be, but probably only if it has play in it causing it to move without you adjusting the throttle.

[@xtrlilbroxtr5563]

Cheers mate, ill have another look on the weekend. thanks for the reply and the vids. its a great resource for us amateurs.

[@DanWebster]

I took a socket and ran a carriage bolt up through the 3/8 drive and ran a nut and washer on it so I could attach that to an electric drill. Saves wearing out your ass snatching on the rope all day. helps suck all the crap out the motor also. just a suggestion. -PawPaw

[@debeeriz]

with all the dunkings an ultrasonic cleaner might be helpful

[@nrtallen]

If anybody reads this can you tell me why I still have a hiccup at High Rev but praise the Lord it will crank and run

[@carlglassmeyer8425]

I didn't see you check the transmission oil?

[@DangarMarine]

The gearbox is underwater the whole time the motor is running, it isn't affected by sinking.

Missing 16:00 plz teching fule pumps in yamaha pls

[@OwensBoatClub]

Some asshole stole my 12' dinghy and Evinrude 15hp a few years ago. they were so slack that it ended up on the rocks in Pittwater. The motor had been separated from the boat due to the surf action. We found the motor under the water in about 4' of water on the beach. This was late in the evening..so we hosed it down as best as we could and then found a big Sulu bin (large Plastic recycling bin) which we filled with fresh water.. We then turned the motor upside down into the bin full of water and let it soak overnight.. we then took the motor to the mechanic and he had it up and running within the hour.. carb was chocka block full of sand. The motor was back on the boat by midday and it's been going perfectly for the three years since..

[@DangarMarine]

Ah, a local boater. :) Yes, if treated properly and quickly, motors can fortunately go on to have a long healthy life. It was good work to keep it submerged in fresh water until the repair could happen.

[@geetarnut]

+Dangar Marine Great video!!! I'm a 27 year outboard tech, since 1988! You were very thorough,, and methodic,, which is the ONLY way to service an outboard motor,, especially 2 strokers! I've had my share of submerged outboards,,, and one in particular, a 2000 model Johnson 15 h.p. that sank around 2 pm, and began to seize up at the crank shaft journals by around 7pm!!! That's how fast it happens!!! I immediately disassembled the entire powerhead just to ensure a thorough clean out/relube! It's nice to see another motor-head at work!!! Cheers!!!

[@DangarMarine]

Sonny Cannon Thanks Sonny, appreciate your kind words. I probably could have done more to that motor but I'm pleased to say it is still running nicely today. :)

[@geetarnut]

+Dangar Marine Well,, don't blame yourself,, because even "on a GOOD day" outboards are a royal pain in the Bass!!! LOL!!!

[@DangarMarine]

You're not wrong there. Aluminium block, stainless bolts, salt water. What could go wrong! ;)

[@Nightstalker350119]

If their is water in the carb then it needs a full rebuild because the water and the ethanol gum everything to hell. The squeaking of the motor, sounds like the rings are shot or the cylinders are scored, sounds horrible.

[@DangarMarine]

That sound is just the reed valves. This motor still runs fine years later. If it is cleaned soon enough cleaning the carb out is enough. Rebuild kits are mostly about seals and gaskets and replacing jets if they have truely corroded.

[@Nightstalker350119]

So that's what that noise is, Ill have to go research reed valves.

[@JohnODonovan1]

Sounds like you scared the chicken away

[@РамзанЖамалдаев-в1ж]

Do you guys need an assistant?

[@DangarMarine]

I certainly need more days in the week!

[@williamriley2528]

Stu... You need to buy yourself a microphone...!

[@DangarMarine]

Bought a good one a few years ago now, this is quite an old video.

[@ailtonpessoa702]

Muito bom não falo inglês mas entendo tudo

[@DangarMarine]

Obrigado!

[@TheRainemt]

what do you mean by 2 stroke oil? Like can i put petrol in? Im new to this

[@TheRainemt]

would WD-40 work?

[@DangarMarine]

Two stroke oil is the oil you put in the petrol of a two stroke outboard (www.nmma.org/certification/oil/tc-w3) WD-40 would be better than petrol as it is designed to displace water was well as lubricate and protect.

[@TheRainemt]

so can i put oil and WD-40 in it?

[@DangarMarine]

Yes. Don't fill it right up or anything, but you can put both in the cylinders to help them free up.

[@TheRainemt]

thanks so much mate ur a life saver

[@shanwan321]

Thanks for going into the details. 85hp submerged in salt water for weeks. Mechanic said no hope. May Allāh(God) guides us, and sustains your addorable child.

[@DangarMarine]

+Be Happy Thanks mate. Personally I think it's always worth a shot. Is it still underwater? The real damage begins when it comes out into the air.

[@stanpatterson5033]

Only my opinion, but for the price of a replacement in that HP range, I'd have gone ahead and opened it up and looked thoroughly at everything and given it a kick (so-to-speak). I can't imagine that I'd rather part with an old friend and a lot of my money before at least taking a look, but it is true, the corrosion really takes off if it just gets pulled out and left to sit dry. Even still, I would take it on as a learning opportunity, if for nothing else than to gain knowledge of what really happens in there. Again, just my opinion.

[@JohnODonovan1]

What's metho exactly ? Is that a branded name?

[@DangarMarine]

Sorry, it's what we shorten methylated spirits to.

[@stanpatterson5033]

Same as methyl hydrate, methyl alcohol, methanol. Highly poisonous if consumed by people or animals, but one of the handiest substances to have around a shop for a wide variety of purposes. It has been my experience that methyl alcohol eats through ice/moisture in places where you don't want it, like airlines, air brake systems. Before the advent of mechanical/chemical air dryers, they put alcohol evaporators into compressed air systems that would experience very wet and very cold climates to deal with elimination of moisture in the system. Also in cold climates, adding small amounts of methyl to regular gasoline helps prevent the moisture in gas lines/tanks. Nowadays, in North America, a lot of fuel is blended (some high, some low) with ethanol, which essentially replaces the need for methyl to be added to gasoline in very cold weather.

[@peterjames2004]

didnt see you take the needle out of the float and check it

[@DangarMarine]

I can't remember now but I have a full video on carb cleaning so I think the idea was to link to that for a detailed clean. Either way you are right, getting water out from everywhere in the carb is important.

[@peterjames2004]

i only say this because on occaisions i have had 2 stroke bikes in which no fuel was coming through to the engine and 9 times out of 10 it was blocked at the float valve .. nice vid though twas only me being a sod ,,all the best pete

[@DangarMarine]

No worries Pete, it only takes one thing to be blocked for the whole thing to stop working so it's sure worth checking everything to save pulling your hair out down the track. :)

[@HorsleyLandy88]

Just prime with raw fuel, then you should get it to fire

[@hatteraslabuf]

Metho? What is that?

[@DangarMarine]

Methylated spirits.

[@alannapartin336]

all i wanna know is what is in your chillybin.... and why arent we consuming one whil w work

[@DangarMarine]

Coopers beer!

[@alannapartin336]

[@hopebear06]

Esky.

[@tomharrell1954]

You did the vid all wrong!!!! No beer

[@DangarMarine]

What was I thinking?!
