Good To Know

Q: Is this an original Sea-Doo part? A: This is an aftermarket valve cover gasket made to fit the 420950820 application, not an original brand item. Confirm your part number before ordering.

Q: Can I reuse this gasket after removal? A: A valve cover gasket is typically a single-use seal and should be replaced once the cover is removed. Reusing a compressed gasket can lead to oil seepage.

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