Good To Know

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

Q: Should the mating surfaces be cleaned before installing this gasket? A: Yes, both the pump housing and block surfaces should be clean and flat so the gasket seals properly. Reused or damaged gaskets can cause coolant leaks and overheating.

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