Good To Know

Q: Is this an original Sea-Doo part? A: This is an aftermarket head gasket that cross-references OEM number 420950772, not an original brand product.

Q: Should head bolts be replaced at the same time? A: Follow the service manual torque sequence and inspect head bolts for stretch before reuse, replacing them if they are out of spec.
