Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket complete crankshaft assembly designed to fit Sea-Doo machines running the Rotax 1503 engine. It is not manufactured by Sea-Doo.

Q: Do I need any other parts when installing this crankshaft? A: A crankshaft install typically calls for new gaskets, seals, and bearings to complete the bottom-end rebuild. Confirm all supporting parts before starting the job.
