Anyone wanna see me rebuild my blown seadoo 951 di

Like the title shows, taking on a new project just cause I have so much time on my hands. Was out for a sunday morning ride and she was purring like a kitten at 50 mph when all of a sudden she went to sleep never to awaken. Because I own a compressor, a few air tools, and a keen sense to know how things work I'm diving in. I back her into the garage plug the comp in and bam shes apart

The seat off , spark plugs exposed, should I continue? am I over my head already?

Top of cylinders, right one looks as tho it may have been a little hotter, or lean, but why???? Oh gratuitous pic of air tool to save my wrists undoing jug bolts

[DOCDRS]

Jugs removed , uh oh what have I found


DSCF0817 by docdrs, on Flickr

A hole in the right piston and massaged rings , now i know why that rave valve looked knarled

[DOCDRS]

Pistons removed and UH oh I dropped a wrist pin coller and some roller bearings as I removed the first piston
Where did they go? Into the crankcase.......most likely

[DOCDRS]

Yep they were in the crankcase.....all parts accounted for 4 wrist pin collars and 72 roller bearings

[DOCDRS]

The sleeve in the jug was scored, so off to the machine shop to get straightened, bored and oversized.....looks like .02 over so pistons are ordered and on their way..... should be here tomorrow for final sleeve honing and fitting .......hopefully I can start the reassemble process wednesday......maybe on the water for the weekend note on cleaning of the crankcase good oil flow was noted into the case so hopefully it was just old age that blew the piston
