Good To Know

Q: Is this an original Sea-Doo part? A: No, it is an aftermarket valve cover gasket that cross-references OEM number 420950820. Always confirm your model and part number before ordering.

Q: Can I reuse the old gasket? A: A valve cover gasket is normally replaced once removed, since a used gasket may not seal properly again. Installing a fresh gasket helps prevent oil leaks.
