    Default 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 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
