Default Boat sunk, but Yamaha still running great

My 16í aluminum boat got under the dock and an abnormally high tide came in and flipped it over. Got down the next morning to see the entire boat except for bow under water. Have a 2001 50 Yamaha 2 stroke on her, was fully submerged for at least 6 hours in salt water. Flipped it over with a boat lift, loaded on trailer, mechanic stripped it down, changed fluids cleaned carbs ect. Cranked right up and ran perfect. Actually better now the carb got some cleaning. That engine realistically has over 2,000 hrs on it and still runs strong. Canít beat an older yammy 2 hammer.

Keep running it everyday . . . Don't let it sit. Prepare to have some ignition related issues. Check every terminal end.

Premix or injected?? If injected I'd dump the oil
run it at least an hour or 2 to get all moisture out of bearings

He already had his mechanic work on it and got it running again

Be careful. In my experience itís just a matter of time before she fails.

I agree about running it a lot. I think you'll be okay. I sunk my motor and I know a lot of other guys who have too.

The motor is oil injected, we replaced all the fluids in engine. Iíve ran it for about 8-10 hours total since the sinking. The mechanic did change out a couple relays. The key was getting it to the mechanic ASAP.

yeah I lost a 35 evinrude off the back of the boat a few years back. when I found it I hauled it to shore and got it running again and it ran for the next 3 or so months. then the crank bearing went. this was fresh water too

OP doin it right.. RUN IT. Run it run it run it. And change the fluids again too. Gotta make sure any and all contaminants are out of the motor. The good part about the 2 stroke... Not many places to hide water and crap.

I have a 1994 Johnson 150 on one of my boats that went down in 2006. Still running without any electrical issue except the starter which actually lasted another 3 years before it needed replacing. If you look all of the electrical connections are sealed by O rings which helps a lot.

UPDATE: So 4 months have gone by and havenít had any major issues. My trim motor and fuel pump were on their last leg pre sinking so I have replaced those parts since. Probably 20 hrs on it since the incident.

only problem your going to have is the electrical side of the motor is going to start corroding and you will be replacing those parts. motor and boat electrical!

can probably find something used that has not sunk for a similar amount of $$ to what has been put in restoring

If he buys a used one he has no idea about hours, maintenance, or even if it’s been sunk. I’d roll the dice on the one I knew before one I didn’t.
Polapea, megabyte99 and MaseTime like this.

Felt awful. Got Boat righted and hauled at our ramp. Worked on it like a mad man for the rest of the weekend.

Still running years later. get to it quick
