Good To Know

Q: Will this rotor fit my Sea-Doo engine? A: It is built as a replacement for OEM 420956675 and is intended for the 1503 engine found in the 2008 Challenger Wake 310. Confirm your engine code and part number before ordering.

Q: Should I replace other oil pump parts at the same time? A: Whenever the pump is opened, inspect the housing and related wear surfaces, since a scored housing will shorten the life of a new rotor. Replacing worn parts together helps restore full oil pressure.

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