Details:

I end up covering partial cost of just about every package send out due to the high shipping these day. Please reach out to me right away. Note 1: this unit is in good usable condition showing normal signs of age, usage and wear. Fast outbound shipping.

It was dinged on one edge and not anything I would allow in an engine. Oil pumps and all associated hardware is included. My wife and I moved our family to Seneca, SC enjoy the beautiful fresh waters of lake cower. If you find yourself in a situation where your product is damaged shipping, miss-shipped, not as stated, etc.

Large oil pump rotor is not included it slipped out of my hands and I bobbled it trying to catch. Excellent packaging. Unit only had 30 total hours. Very nice condition oem standard bore crankcase/block assembly removed from a fresh water 2017 Seadoo Gti se 90 with the 900 Ace engine.

I ran a 240 grit hone for 20 seconds in each cylinder to remove the glazing. However, none of those experiences allowed me to work with my absolute favorite marine toy. My wife and I still ride stand up skis to this day. This is a very clean cylinder.

Please do your research and reach out to me with fitment questions before committing a purchase. I source, buy, disassemble, clean, picture, list and ship every part myself.
