WSM Piston Assembly - Sea-Doo - Standard 010-818PK

A piston assembly is the heart of your Sea-Doo engine—responsible for converting combustion into horsepower and handling extreme thermal stress. This WSM assembly meets or exceeds OEM specifications while incorporating advanced engineering that reduces friction, lowers operating temperatures, and extends component life. Whether you're replacing a worn piston or building a high-performance engine, ordering one assembly per cylinder ensures consistent performance across all cylinders.

The MOS2 coating on the skirts is the standout feature here. This nonabrasive, molybdenum disulfide treatment doesn't just sit on the surface—it actively draws heat away from the piston and channels it out through the walls, reducing friction and heat buildup. Combined with specially hardened ring groove tops that resist deformation under load, you get a piston that runs cooler, lasts longer, and delivers measurable gains in reliability and power output.
