It is built with an aluminum construction and finished in white to match OEM appearance under the flywheel. This stator is designed as a direct fit for a specific set of Mercury\/Mariner outboard applications identified by horsepower and engine serial number, so confirming your outboard's serial number against the fitment list below is the surest way to order the correct part. It is intended for gasoline-fueled, 4 stroke outboard engines using transom mounting, including outboards commonly used on inflatable boats. The stator functions as a wear-and-tear electrical component, and installing a correctly fitted replacement restores reliable spark and charging performance when the original unit fails or weakens with age. Because it is engineered to meet or exceed the performance of the original equipment part it replaces, it is a straightforward swap for the OEM stator on the applications listed, using the same mounting points and electrical connections as the components it replaces.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
