Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket oil pump rotor made to fit Sea-Doo 1503 engines and cross-referenced to OEM number 420956675. Confirm your engine code and part number before ordering.

Q: Should I replace the whole oil pump or just the rotor? A: That depends on the condition of the pump housing and internal clearances. If the housing shows scoring or wear, replacing the complete assembly is often the safer route.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
