Hello all me again… engine was partially submerged, did the usual, plugs out turn flywheel by hand get as much water out as possible then water out treatment turn again, then oil in each cylinder and turn again, took battery out and charged up( had died during storm so bilge stopped working) went to start it up and sounded like the starter was having a hard time turning(plugs out engine and starter were fine) after a bit of starting attempts I went back to look at the engine and there was smoke coming from the bottom of the starter motor, then to my horror I noticed that the positive battery cable and been so hot the lead melted out of the cable and melted the top of the battery ….thoughts?

Your starter is beyond dead. Internally shorted.

Was this salt water or fresh?

Fresh water

Thanks Tim that’s what I thought, I ordered a new one will take a week to come in, should I add some oil to the cylinders and rotate engine periodically while I wait to keep them from rusting?

My preference is CRC Marine. Something that can get under the water.

 

[paulc229]

Thanks Tim, unfortunately that isn’t readily available in my area, is there anything from say Canadian tire that would suffice?

The best thing you can do to a submerged, 2-stroke, engine... is get all the water out as soon as possible... and get it started and running up-to-temperature again to drive off any remaining moisture in the engine. I saved a jetski engine this season that sat flooded for 2 days.

Short of getting the engine running, any sort of engine fogging oil spray would be better than nothing. Stabil makes a fogging oil... other do also. Used mostly to winterize an engine. It's good at coating an engine with oil to prevent corrosion. I use it on my engines (winterizing).

Cheers!

Not a big fan, but WD-40. Plenty of it.

Ok so, got the new starter today, had been adding we to the cylinders periodically while waiting on the starter and turning engine over manually, . Installed new starter bumped the engine over without plugs to get any residual moisture out, put plugs in and it wanted to fire and started a few times only ran for 2 seconds, then died, took the plugs out and they had a white fluid on them I’m assuming still water in there somewhere? Dried them off and tried again, started to turn over and then a loud thunk, my heart dropped, doesn’t look like what I thought it was. Still spins over with out plugs. Pulled the copper nut off of the vst(I think)(silver box that low pressure fuel pump goes to) and emptied it and filled it a few times, a bit milky. Did change the oil and syphoned some of the gas out of the tank to check it and it see by ms fine, as did the oil. Where else should I look?

 

[paulc229]

update, got the engine "running" butonly for a few seconds then dies, checked pressure at the vst and 0, checked the connections for corrosian and cleaned them up but they looked fine, i do get fuel when i remove the brass screw, maybe 1 cup or so maybe a little less.

Did you have the wires for vst pump disconnected? Polarity matters. The pump will run wired backward, but will only build pressure wired correctly.

 

[paulc229]

I only took the positive off because I couldn’t see its condition, the negative looked fine so I didn’t take it off

How about the wires that connect to the pump? They are plug-ins that could have bad connections.

Have you cleaned out the tank? You may have a lot of water in there. If you have gas/ethanol there is no way to make the water separate from gas/ethanol.
Have you tried a 6 gallon tank? Keep trying to get it running, but don't burn up your starter. Make sure your kill switch works properly.

 

[paulc229]

So I set up a secondary fuel tank and took some video, I noticed that the exhaust tubes are a bit collapsed and if you look at the one, it’s pulsing and when the thud comes in water splashes out the rear can’t forgive out how to post a video but both exhaust tubes seem not fully round and there will be a thud and then water splashes out from exhaust underwater? If that makes sense

 

[ripcuda]

The thud followed by water splashes sounds like the engine pushing out a bunch of water out of the exhaust mufflers (aka waterboxes). Those might be extra full from the submerging and the engine is maybe building pressure then coughs hard (thud) and expels a bunch of water from them.

Is the boat still in the water... or on the trailer?

 

[paulc229]

thats what i was thinking ripcuda, how would i go about getting that water out, it doesnt come out throught spark plug holes, i get nothing from them? still in the water, its a bitch to get out without motor running, have to paddle it all the way across the lake

 

[ripcuda]

You'd have to disconnect the two large hoses connected to each waterbox and remove them to fully drain them. In normal operations, they will always have some water in them... but they likely have more than normal after the submerging. If you got the engine running and got the rpms high enough... the force of the exhaust would blow the excess water out.

 

[paulc229]

here is the video i think

 

[paulc229]

the problem is i cant get it rev up, it only runs for about 3-4 seconds then dies

 

[ripcuda]

Yeah... you'll have to pull the waterboxes and get them drained. Might help your running issue too if the engine is choking off on the blocked exhaust.

 

[paulc229]

by water boxes i assume you mean the ones on the end of the exhaust tubes that look like a muffler?

 

[ripcuda]

Yes, the mufflers (aka waterboxes). One big hose coming one, one big hose exiting. couple rubber straps holding it in its cradle.

 

[paulc229]

Thanks, got the one hose off and could hear water sloshing in side the water box, cut couldn’t get it out, is it safe the take the box completely off while the boat is in the water or will the engine compartment start filling with water?

 

[paulc229]

might be a bad idea... but could i hook up a leaf blower to the exhaust hose and try to blow the water out?...lol
