Good To Know

Q: What is the role of an oil pump rotor in a Sea-Doo? A: It rotates within the oil pump to move oil from the sump into the engine's lubrication passages. Reduced oil pressure or internal wear often points to a rotor that needs replacement.

Q: When should the oil pump rotor be replaced? A: Replacement is typical during an engine rebuild or when low oil pressure or debris suggests internal wear. Inspecting the rotor whenever the pump is opened is good practice.

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