Good To Know

Q: Is this an original Sea-Doo part? A: It is an aftermarket replacement built to cross-reference OEM part 420956675, and it is branded for Sea-Doo fitment only. Always verify your engine serial number before ordering.

Q: Can I reuse the old rotor if it looks fine? A: Worn rotor lobes reduce oil pressure even when they appear serviceable, so replacement during engine work is the safer path. Inspect the pump housing for scoring at the same time.

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