Q: Is this an original Sea-Doo part? A: This is an aftermarket replacement for OEM part 420911558, not an original Sea-Doo component. It is designed to match the fit and function of the factory cover.

Q: What should I check before installing this cover? A: Inspect the power valve housing for cracks, clean the mating surface, and confirm the correct gasket is used. Verify your engine serial number falls within the 951 range before ordering.
