787 engine cyl chambers filled with oil

[Bryan1102]

Hello there guys I'm new to the sea doo community , I just acquired an 99 challenger one of the engines gets the cylinders filled or partially filled with oil at least there's oil present on them and i could not get it to turn with spark plugs on obviously hydro lock now it seems that got cleared out and I attempt to start it but it would just do like an old Chevy nova out of time , and quit smoke will come out of tha carbs , at least I got it to turn with plugs on but now I'm getting this , please help

Your crank seals are probably leaking, there's really no cure except a new crank. For the short term you can pinch off the oil line to that engine when not in use.

New crank or seals ??

The seals are in the crank assembly. Most typically you would replace the crank to replace the seals.

Brock 1 , is it normal that it does try to start and it quits and then smoke comes out of the carbs ,i took the oil feed line off the block and that is how i got it to clear some of the oil so i could even cranked with plugs , will the brass pinion go out just with start attempts ,im not a sea doo mechanic but i dont think so please help thanks .....
