The best way to confirm fitment is to check your engine's OEM part number against the ones listed in our Part Number Matrix (61A-W0078-A1\/A2\/A3-00). You can also review the Engine \u0026amp; Model Compatibility table, but always cross-reference the part number for accuracy.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhat are the signs of a failing water pump impeller?\u003c\/summary\u003e\n  \u003cp\u003eCommon signs include an engine that is overheating at idle or low speeds, a weak or non-existent \"telltale\" water stream, or a dry, cracked, or brittle impeller upon inspection.

This interval can be shorter if you operate frequently in saltwater or sandy\/silty conditions.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eIs any special grease needed for installation?\u003c\/summary\u003e\n  \u003cp\u003eYes, applying a light coat of marine-grade waterproof grease or dish soap to the inside of the pump cup and on the impeller vanes can ease installation and provide a better initial seal.
