water in engine turned into rust, HELP!!!!

[zachattack2795@aol.com]

last year i went to my cottage to find my 1996 gsx half sunken. the rear end was on the bottom of the lake (2ft). we got it out and it cranked but wouldnt start. after letting it sit for the winter the engine is seized, the pto wont move and there is rust in the cylinder. would wd-40 be enough? i only have $500 to put into the ski.

Hi Zach,
Even if you were to do all the work yourself your looking at over 500$. I would say you will need at the least new crank, new seals, new counter balance shaft plus bearings and cylinders honed all of this depending on how much rust there is in there. I would try putting a very good amount of 2 stroke injector oil in cylinders and try to spin shaft without plugs in.
You have nothing to lose. You really prob. need replacement motor with your core. Good luck.

You prob. should have fogged it really good, before the winter and when it wouldn't start but would crank.

but would the water have gotten past the piston rings?

That engine is more than likely toast...I have seen people leave water in the engine and not run it for a week and it rusted the bearings and crank. Any time you get the engine flooded with water you need to get it running and get it to normal operating temperature to get all the water out of the engine.
Good luck with it now, it will more than likely need to be replaced with a re-manufactured engine. Should cost ya just under $1000.00 when finished.

would the engine rebuild kit in the link be enough? http://seadootech.com/787/seadoo787cat.htm

 

[kustomkarl]

It might be ...you need to pull the engine and pull the heads and cylinders to see what damage is done to the engine. If it had water in it over the winter and it froze it might have a crack in the water jacket or cases too...

do you need a balanced crank or would non balanced work? i dont know anything about balancing

 

[timmyboy76]

New/reman cranks should be balanced/tru from manufacturer. If doing rebuild yourself, watch for piston weight, dont want it too far off, should be on box...:cheers:

take the whole engine apart before you buy a thing. you MIGHT get by with honing the cyls and new rings. i doubt it. you NEED a crankshaft. you do not want a used one-they are prone to oil seal failure, and crank has to be pressed apart to change seals. take the flywheel off the front before you take engine apart. that could be the problem. it is not as well sealed as wngine itself. i sank a 580. 3 years later i tore the top end off-broke head bolts and threw away a still runnable top end-because my flywheel was rusted to the stator. your best bet might be a used motor with your current budget.
