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.
