Good To Know

Q: How many O-rings should I order for a full rebuild? A: Most 951 RAVE valve setups use one O-ring per valve, so confirm how many valves your engine has before ordering. Inspecting the old seals for hardening or flattening helps you decide what to replace.

Q: Does this O-ring fit other Sea-Doo models? A: It is listed for the RX X 951, and compatibility can vary by engine and serial number. Compare the OEM number 420931670 against your parts diagram before purchase.

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