Help - boat nearly sank, engines flooded

[FLJetBoater]

Update: there was definitely water in the airbox. About 1L. Pumped out.
air intake had some water that dripped out, maybe a cup full.
Rechecked for water in cylinders and they are dry.
still Wont start. Turns over but won’t catch.
If the new spark plugs got wet because more water went in would they be ruined too?

I think I may try the other engine and see if I get the same results. If so maybe it is the fuel?

Are you sure you got all the water out of the intake side? And is it kicking over sounding like it might start or just cranking?

 

[Bruce]

Did you reinstall the wet air filter?

I have the intake hose off the throttle body, so even if there was water in there it wouldn’t be doing anything.

it’s basically just cranking, but every couple seconds or so it starts to rumble like it’s going to start.

 

[FLJetBoater]

Did you reinstall the wet air filter?

No there is no filter in there at the moment.

 

[Scottintexas]

did you spray any starter fluid, fogging oil etc.. into the spark plug hole and then try to crank it ??
or maybe into the air inlet,

if the cylinders don't have sitting water I would think doing that would at least get them to fire momentarily, if it didn't work I might think I wasn't getting a spark and would confirm that,

The time clock is ticking fast on saving the engine(s). You need to get the boat to somebody who knows how to get her running and do the boil out procedure. Which is running and changing the oil multiple times. That salt water inside the engine is not going to wait to start rusting your cylinders.

This time of year, and this area.... if he has the time and knowledge he's is better off doing it himself. I doubt anyone in the area can get to it in the next 24-48 hours.

OP, have you changed the oil?

No will try that now

I agree and like Adrian said everywhere here is booked for at least a week. I’ve already called and I’ll keep it until my appointment. No sense dropping it off for it to sit there

Yes oil is changed...only once because I haven’t been able to get them started to mix it to change it again.

The best thing you can do is to keep trying until it fires up. Just letting it sit is what will kill it with the water in the engine. Starting fluid my be your best friend at this moment if it is indeed trying to start occasionally and your not pumping water out of the cylinders anymore.

VERY unlikely that you have water in the fuel. If water got in the tank then there would have been a terrible smell of fumes before all of this even started due to either the filler neck or the sending units not being sealed and gas being leaked as it was being sloshed around during trailering or while under way.

I'm just wondering if there is still water in the crankcase (ie - did you add oil back before all the water was eliminated in the intakes etc)? Wonder if pulling the drain would be worth doing? https://jetboaters.net/threads/oil-change-on-mr-1-how-to-perform-a-complete-drain.3805/

Did the fuel vent line go below the water?

 

[AZMark]

Water on the plugs will keep them from sparking until it dries but it won’t ruin them right away.

You mentioned recent service a couple times but also that your exhaust was missing a hold down strap. Sounds like sloppy work & very possibly the root of your problem.

Port side engine started after going through the same process. I ran it for about 30 seconds then stopped it to move it to where I have water. Now it won’t start lol. Chugs much better than the stbd but won’t catch, going to try and put some starting fluid in it

I guess it’s possible. Water was 6” over the batteries. I don’t think the very end of the vent would have been though.

Well I should say it did start again briefly. Enough time for me to jump off the boat to go flip the water on and it stalled out

Yer gaining

Don't forget that it's going to take quite a bit before it runs anywhere near smooth. Your trying to burn fuel & water off at the same time until it runs at temp for quite a while.

I wouldn’t worry about getting the hose turned on and off at this point. If it’s stalling you might end up pumping more water into it from the hose after it stalls.
You’re not going to overheat a cold engine very fast.

@FLJetBoater I use these so I can just turn the house off and on without jumping out of the boat.
