Good To Know

Q: Is this gasket a genuine Sea-Doo part? A: This is an aftermarket replacement gasket built to fit for Sea-Doo watercraft, not an original factory part. It is designed to match the OEM part number for proper fitment.

Q: Should I replace this gasket every time the housing is removed? A: Yes, a fresh gasket is recommended any time the housing is taken off to prevent coolant leaks. Reusing an old gasket risks poor sealing.

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