This piston kit is developed for Yamaha 40HP two-stroke outboard motors with a 78mm standard cylinder bore. It matches piston pin OEM 6F5-11633-00 to lock piston assembly firmly. Precision machining ensures suitable clearance inside cylinders. Wear-resistant alloy materials endure continuous marine operation and prevent gas blow-by. Dimensions comply with OEM standards for simple assembly. This piston set recovers sufficient compression and maintains stable power output during navigation.
