1992 seadoo xp starter stuck and siezed engine please help

[Donnym25]

So piston blew up into 1000 plus pieces and is all throughout bottom half of engine.

Is there supposed to be grease in the crankshaft there isnt a drop of it not even on the wrist bearings which doesnt make sense.

The 2nd ski clone ski i took apart has a bunch of grease in bottom half and water aslo so there was a leak in gasket somwhere..

Anyone with anynore info on what happened or anything

Let me kno please

There was only half a piston left....

Is there supposed to be grease in bottom half of engine or does this get lube by oil injection?

No grease on anything but there should be a little 2 stroke oil. These don't use oil in the sump like a 4 stroke. It is just a thin film of oil supplied by the injection pump and mixed with the fuel in the intake.

Your crank is shot with the debris that went through it and on the 2nd engine if there is water in the bottom end that crank is shot too.
