Power Valve for Sea-Doo

This power valve, part number 290854540, regulates exhaust timing on the 951 DI engine to sharpen low-end response through the powerband.

Overview

This power valve for Sea-Doo is a direct-fit exhaust timing component built for the 951 DI engine used in RX DI models from 2000 to 2003. The valve opens and closes the exhaust port to tune exhaust flow as RPM rises, helping the engine build power more efficiently. It suits riders replacing a worn or seized valve on their personal watercraft.

Specs At A Glance

Good To Know

Q: Does this power valve fit both cylinders? A: The 951 DI engine uses power valves at the exhaust ports, so confirm how many your specific RX DI requires before ordering. A: Matching the OEM number 290854540 to your machine helps ensure correct fit.

Q: Should power valves be serviced in pairs? A: Many riders inspect and clean all valves at once during top-end service for consistent exhaust timing. Replace any that are seized, scored, or heavily carboned.

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