Good To Know

Q: Is this O-ring a genuine Sea-Doo part? A: It is an aftermarket replacement that cross-references OEM number 420850500, not an original brand product. Confirm your engine and cover match before fitting.

Q: Can I reuse my old O-ring after an oil change? A: Reusing a compressed or hardened O-ring risks leaks at the filter cover. Replacing it during service helps maintain a clean, reliable seal.

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