Ok, so I've been trial running my canoe with a 4HP Evinrude, the other week, there were 3 jet skis running around me and I lost balance right before starting the motor and flipped the entire thing. So trial #6 was a fail.

Now, I can't start the motor, I'm guessing I've got water in the fuel? It's been 3 days (enough time for evaporation). Is there anything else I can do?

I'm going to pick up some water remover, siphon the gas, give it a fresh tank, and hopefully that will take care of it. Any other suggestions? The motor WAS NOT running when I flipped.

Re: Another 'water' motor post...

Yours is a prime situation why all good power boaters should have 50 cal. machine guns mounted on their boats. It's called jet ski repellant. If it has a tank on the mtr open up the gas cap and drain in a bucket. This may also get the h2o out of the carb through the vent. Pull the plugs and crank it over quite a few times to get h20 out of c/c. If you have spark after this with fresh fuel and plugs it should start. Good Luck. One other thing, turn the mtr completly up side down when draining. Been their and done that.

Ditto on using fresh fuel. Make sure you get that motor running promptly, or it will rust up, and be junk. Run it for 45min to make sure it is dried out.

If the motor was completly submersed it is more than likely a rusted pile of junk now. Does it turn over? Usually when they are submersed they have to be torn right away.

BK - if they are submerged in fresh water, you can get the water out of them, and run them for a while to dry them out, w/o disassembly. Salt water means tear down.

I do agree that you need to act promptly if you want to save them.

Re: Another 'water' motor post...

Had my first boat beached at a nearby lake, a storm came up that night and sank the rear of the boat. The Merc. 25 was half way under water the next morning. The water didn't get high enough to get in the starter, but the motor had swallowed a bunch.
Took plugs out, and drained the carb, made a spray bottle of mix and fogged the motor out good using the starter. Put the thing back together and ran for 4 hrs. Never had any problem relating to the sinking after that. Got Lucky

Re: Another 'water' motor post...

I am wondering why , a boat motor would be considered a piece of junk , because it took a little dip in the water.:rolleyes:


The other day we pulled a 1973 Evinrude fisherman model 6302s out of the water with the anchor

The motor was in the water a long time and the water was really silt filled. we brought it home with 5 inch's of mud casing most exposed surfaces and pressure washed it as we disassembled it . we did not care about where we sprayed the water except for the carb .

The shift lever was broken, and the throttle was stuck so that the tiller would not turn, or fold

the flywheel would not turn and the engine would not tilt

I am guessing that this motor was in the water for at least six month.

Anyway we used an air hose to blow the water out of the cylinders and sprayed them down with gas and oil mix

we took off the old coils , condensers and points

we replaced the rotted fuel lines and forced fresh gas through the carb , and out the drain at the bottom

we use a rubber mallet to break lose the stuck parts and sprayed everything with lube

the water pump impeller is rotted , and it was full of mud , we need to get a new one

anyway the motor runs as it sits right now, but because the impeller was bad we have not run it more than a few minutes 30 seconds at a time

It might need a carb rebuild , and to be honest I was surprised that it started without a complete carb deep cleaning.


My fear is that with the amount of silt that was everywhere else , the crankcase is probably coated with a small layer of silt as well

I am not going to invest in a rebuild of the motor it will either hold together , or it won't

our investment so far , 2 hours , some spare old parts that we took off other motors and replaced with new, one can of lube,replaced the lower unit oil,19 dollars for a new impeller.


I think now that the best thing for this motor would be run it , and run it some more

on a further note , I was looking at google earth the other day , and could clearly see 20 boats sunk in our local lake it is only 26 feet deep at the deepest point who knows where this could lead lol

Update on the six that sank

it runs great , until you try to slow it down , I am sure now that the carb needs to be blown out.


it will run great as you back off the throttle to shift , then it starts to spit and stalls

disassemble the carb find a syringe (dont need the needle part) and chase all the fuel circuits with alcohol. Thid will help get rid of any water left in the carb.
