Good To Know

Q: Does this gasket require sealant during installation? A: Follow the service manual for your Sea-Doo model, as some housing gaskets install dry while others call for a thin sealant film. A clean, flat mating surface is essential either way.

Q: How do I know the gasket needs replacing? A: Coolant weeping at the pump housing, a crusty residue around the mating surface, or a gasket that has hardened are all signs it is time for replacement.

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