HELP ! I laid a tower boat on it's side yesterday The 150 HP Yamaha was 1/2 under water for 2 min?

Question

When I got home I pulled the plugs and bumped the key water came out.I then sprayed a small amount of transmission fluid in . and cranked away.After that I put the plugs back in drained the water seperator and after a bit she fired up!! Today I was going to go to a fresh water lake and run her but is this the right thing to do ???????

Answer 1

It should be fine.

In the future, if you submerge an engine again. You'll want to pull the plugs, drain the water as best you can, ground the plug wires, and try to start it with no plugs in it (obviously it won't start). This helps push the remaining water out of the engine and since the air and water escapes from the plug hole no damage can occur.

Then put one plug back in and try to crank it, inspect that plug and wipe water off as necessary. Repeat for the other cylinder(s). Once you get it going again your best bet is to run it for 10-15 minutes so the heat can get rid of the remaining condensation. It may run a little rough at first. One or two days of water sitting in there won't hurt it but more than that and you could be looking at rust on the cylinder walls and pistons.

Answer 2

I not see why it would not be OK. You may want to put something in the fuel tank like Injector/carburetor cleaner. It will mix with any remaining water to help it burn it out. My pickup has a bad idea of getting water in the fuel in a hard rain and it miss and sputter. I can add a bottle of Carb cleaner and it clear right up. Also, you may go to a parts store and ask for "Sea Foam" it great for outboards and will help burn the water AND clean carbon out of the engine. So, you get 2 for one!

Answer 3

AFT is not an oil so it does nothing you have to let it idle for 30 minutes before running it hard so spray with CRC>An was it salt or fresh water, fresh water your OK salt needs more attention>

Answer 4

It would be more helpful if you were more specific about the engine. Is it 2 or 4 stroke? Is it carburated or fuel injected? If it's 2-stroke carburated you should be ok. Also did you sink it in fresh or salt water? Either way your biggest concern will probably be your fuel tank. Running the engine will be good for it, just try to have a backup plan in case you have a problem, like another boat with you. Post more info and i'll try to help more.

Answer 5

if it started, it's okay.
