This engine block came out of 2001 SEADOO GTI that was a fresh water ski. Even though there is no grinding noise coming out of the crank, I would recommend getting a crankshaft to be replaced. I have a video of me spinning it and I can share that video if you would like to DM me.
Basically selling this crank case with a decent core crank, and PTO.
Thank you for looking!
