Industrial P420254682 Exhaust Valve

OEM Sea-Doo exhaust valve, 31 mm diameter, part number 420254682 (also cataloged as 420-254-682; cross-listed variants include 420254680/420-254-680 in some catalogs). This genuine replacement valve is designed for Sea-Doo watercraft exhaust systems and is used to regulate exhaust flow from the engine into the jet-drive, helping maintain proper timing and prevent backflow. The 31 mm size corresponds to the standard Sea-Doo exhaust valve specification, and the part is commonly listed as an OEM Sea-Doo component by BRP and multiple retailers. Replacing a worn or malfunctioning exhaust valve restores normal exhaust flow, supports consistent engine performance, and helps preserve cooling and overall reliability of the watercraft. When installing, verify compatibility with your specific Sea-Doo model by matching the OEM part number, and ensure correct seating with the valve seat and seals to maintain exhaust integrity and water intrusion protection. This valve is widely stocked by BRP-sea-doo part distributors and aftermarket retailers under the 420254682 designation, providing a direct-fit option for eligible exhaust assemblies.
