Rotary Valve for Sea-Doo GSX 800

This rotary valve is a replacement intake timing component that regulates the air-fuel charge entering the crankcase on the Sea-Doo GSX 800.

This rotary valve is intended for riders servicing or rebuilding the top end of a 1996 through 1997 GSX 800.

Good To Know

Q: Does this rotary valve come with the cover or shaft? A: This listing covers the rotary valve disc only, so reuse your existing cover and shaft unless they show wear. Q: Can I install this without splitting the engine case? A: The rotary valve sits inside the crankcase, so the case must be opened for installation. Confirm your model year and engine code 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.
