420939130 Power Valve Spring for Sea-Doo GTX DI 951 2000-2003

Power Valve Spring for Sea-Doo

This power valve spring works with the RAVE exhaust power valve system on 951 DI engines, giving the valve the tension it needs to open and close at the right RPM, and it matches OEM part number 420939130.

Overview

This power valve spring is a direct-fit replacement for the RAVE valve assembly used on Sea-Doo 951 DI engines. The spring controls when the exhaust power valve opens, which affects how the engine builds power through the rev range. It is built for riders and mechanics servicing 951 DI powered watercraft.

Good To Know

Q: How do I know this spring fits my watercraft? A: Match your engine to the 951 DI platform and cross-check OEM part number 420939130 before ordering. Serial number and model year can affect fitment, so verifying against your machine is recommended.

Q: Should I replace one spring or both? A: Power valves come in pairs, so replacing both springs at once keeps tension even across the engine. If only one has failed, inspecting the other for fatigue is a good practice.

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