Yamaha 6M6-11636-01-00 Piston

Description:

The Yamaha 6M6-11636-01-00 Piston is a combustion component used in marine engine crankshaft and cylinder systems. Commonly installed in Yamaha WaveRunner 650 series engines such as SuperJet, VXR, and WaveRunner III models to compress the air-fuel mixture for engine operation. Maintenance teams and marine technicians use this part for repair, rebuild, and performance restoration of worn or damaged piston assemblies.

Applications:

The Yamaha 6M6-11636-01-00 Piston is used in Yamaha marine engine assemblies where efficient combustion and compression are critical for engine performance. It is commonly found in Yamaha 650cc WaveRunner engines across models such as WR650, SJ650, and VXR, operating within the cylinder to convert combustion pressure into mechanical motion. This piston is often used in engine rebuilds, especially in oversize (.50mm O/S) configurations to restore cylinder tolerances after wear or machining.
