Good To Know

Q: Is this an original Sea-Doo gasket? A: It is an aftermarket water pump housing gasket that cross-references OEM 420950840, not an original Sea-Doo product. Verify the part number before ordering.

Q: Does the pump housing need to be removed to replace this gasket? A: Access depends on the machine, and the housing usually needs to come off to swap the gasket cleanly. Clean both surfaces before reassembly to avoid leaks.

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