This STD piston assembly uses part number 6F6-11631-00-95 and can replace reference PN 6F6-11631-00. It is developed for Yamaha 40HP two-stroke marine outboards E40, E40G and E40J with a 78mm standard cylinder bore. Meticulous fabrication ensures effective sealing and clearance inside cylinder bores. Tempered alloy survives repeated marine service cycles and minimizes compression leakage. OEM-aligned sizes enable simple fitting. It resolves compression failure and guarantees consistent power performance throughout boating.
