Good To Know

Q: Is this an original Sea-Doo part? A: This is an aftermarket water pump housing gasket made to cross-reference OEM part 420950840. It is not an original factory part.

Q: Should the gasket be replaced every time the housing is removed? A: Gaskets are designed for a single installation, so a fresh gasket is recommended whenever the water pump housing is taken off. Reusing a compressed gasket can lead to coolant leaks.

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