Asaki 64X-11636-00 65U-11636-00 Oversize 0.50 Piston Kit 84.50 mm Bore Replacement for Yamaha 760 1200 Series PWC 1996-2005

Restore Your Watercraft’s Power and Compression Bring your marine engine back to peak performance with our 0.50 Oversize Piston Kit (84.50mm Bore). Over time, marine cylinders experience wear that causes a loss of compression and thrust. This precision-machined 0.50 oversize piston is engineered specifically to seal worn cylinders, restoring the factory power profile of your 760cc or 1200cc engine. Built to withstand extreme RPMs and severe combustion temperatures, this kit ensures reliable power generation on the water. Engineered for the Marine Environment Marine engines operate under uniquely harsh conditions. This piston kit is constructed from high-strength, heat-dissipating alloys designed to reduce thermal fatigue during sustained high-speed runs. It also features advanced saltwater corrosion resistance to prevent internal degradation, making it ideal for both freshwater and saltwater applications.
