It is designed for use in a marine environment, where it has to stand up to constant vibration, heat cycling, and exposure to moisture around the powerhead.\u003c\/p\u003e\u003cp\u003eThis stator is compatible with Mercury and Yamaha 25 HP 2-cylinder engines from 1998-2005, 30 and 40 HP 3-cylinder engines from 2002-2005, and 40, 50, and 60 HP 4-cylinder engines from 2002-2005, on Electric Start, 4-Stroke models with a 4-Pin Connector. It is a direct fit for these engine families, delivering the same 16 Amp output as the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003eBecause charging systems on these Mercury and Yamaha outboards were produced under a long list of part numbers over the years, this stator is cross-referenced to the OEM numbers below so you can confirm it matches what is currently on your engine before ordering.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
