Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: This oil pump rotor is an aftermarket replacement made for Sea-Doo 1503 applications and cross-references OEM number 420956675. Always confirm the number on your old part matches before ordering.

Q: Can I install this rotor without changing the pump housing? A: The rotor is designed to seat in the oil pump assembly, but the housing and other pump parts should be inspected for wear at the same time. Replacing only the rotor may not restore full oil pressure if the housing is scored.

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