I have an 05 Seadoo GTI 720. broke a few motor mounts engine slid forward, submerged my ski entire engine under water. I was able to flush the water out of the cylinders and get it started to flush the engine. I know I need to replace all four motor mounts. I assume the carbon ring is shot and that is where the water got in when the engine slid forward. I was going to buy a carbon ring repair kit on ebay (carbon ring, O-rings, support rings, & c-clip). Anything else needed to be replaced? Any write-ups on the repair?
