Good To Know

Q: Does this gasket require new head bolts? A: Torque-to-yield head bolts should always be replaced during a head gasket job, and factory torque specs must be followed for a proper seal.

Q: Is this an original Sea-Doo part? A: This is an aftermarket replacement for Sea-Doo that cross-references OEM part 420950772, not an original factory component.

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