    anyone have a 250 ultra crankshaft

    yep another stuffed motor caused by motor being out of alighnment to coupler from new. destroying the thrustwashers at 83hrs cases are scored but i'm getting them moddified to suit a square section of thrustwasher top and bottom cases. crank was crack tested and has deep cracks in the thrust area that are to deep to repair. another seperate issue is a cracked head between no.2&3 cylinders from the exhaust valves through the water jacket.

    i only pulled the motor after noticing the float in the crankshaft as the ski was running perfectly.

    mine will be undergoing crank surgery too @ only 30 hrs , hopefully caught it early enough as no apparrant top end damage , just trying to figure out the cause and how the prop manage to spin off ?!

    not sure where you are going with this? the crank was repairable at a price far outwaying the cost of a replacement. as the labour content would be huge.
