    So I Guess it suck it through the crabs only?? (I Just bought another SeaDoo and That dumps oil down below also)
    The two good clyinder look great can still see the Crosshatch. The MIddle one the rings are seized to the piston and a few groves in the wall not really bad? What do you think?

    So It looks like the the Crank is dry on that cylinder also the bottom bearing seems fine no side to side play more than the rest

    How many hours on engine? Looks like that cylinder needs oversizing or as you say replace sleeve. Before you do that check clearance between pistons and cylinder walls on two others.

    Ill check the clearance and whats the compression supposed to be on a non PV 1200?
    I Was also just thinking about honeing it and throw a used piston inthere and re ring all 3.
    Is the only place it gets oil from in that intake pan in the second pic?
    Can I get the hours off it with out starting it?? only thing it would do is ask for code
