Replacement Part Number
Yamaha 6AH-W0078-00. OEM part numbers are used for identification and compatibility reference only. This is a marine-grade aftermarket replacement, not a genuine Yamaha part, intended to be compatible and interchangeable with the corresponding original component.
Please Check Compatibility
Confirm your engine model, year and original part number before ordering. A similar appearance does not guarantee correct fitment. If you are unsure, contact SSI Marine before purchasing.
