Power Valve for 1997-1999 Sea-Doo SPX 800 - Replaces 290854352

Power Valve for 1997-1999 Sea-Doo SPX 800, a direct replacement for OEM part number 290854352.

The power valve (RAVE valve) changes the height of the exhaust port with engine speed, giving strong low-end torque and full top-end power from the same engine. Carbon build-up or wear can cause the valve to stick, costing performance at either end of the rev range.

When You Need It

• Loss of top-end power or poor low-speed response
• Valve sticking or not moving freely
• Heavy carbon build-up or wear on the valve blade

Fitting Tips

• Clean the power valve regularly to prevent carbon build-up
• Inspect the bellow and seals at the same time
