Good To Know

Q: What does a rotary valve do on a Sea-Doo engine? A: It rotates with the crankshaft to open and close the intake ports, controlling when the air-fuel mixture enters the crankcase. A worn valve disc causes poor sealing and rough running.

Q: Should I replace the valve cover gasket at the same time? A: Yes, the cover gasket is normally replaced whenever the rotary valve is serviced because the original seal is disturbed during removal. Confirm the gasket matches your engine before ordering.

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