Good To Know

Q: Does this gasket fit my 951 engine? A: It is listed for the Sea-Doo Sportster LE 951 from 2000 to 2003 and cross-references 420931702. Confirm your serial number and engine before ordering.

Q: Should the cylinder head be checked before installation? A: Yes, the head and block surfaces should be flat and clean so the gasket seals correctly. Warped surfaces can cause compression leaks even with a new gasket.

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