This piston assembly comes supplied with matching piston pin and retaining circlip, referencing PN 6F6-11631-00 and 6F5-11631-00. It serves as aftermarket replacement for Yamaha 40HP two-stroke marine outboard 40G with a 78mm standard bore. Meticulous machining creates suitable clearance within cylinder bores. Tempered alloy survives repeated marine service cycles and reduces compression leakage. OEM-matched sizes allow quick fitting. It fixes compression loss and guarantees consistent power performance during boating.
