It is designed to restore proper cooling system function when an outboard's water pump impeller and related components have worn out or failed. The kit contains a Sierra 18-3051 impeller (O.E. #395289, qty. 1), the key wear component in an outboard water pump that circulates raw water through the engine's cooling passages to prevent overheating. Because the housing is not included, this kit is intended for rebuilds where the existing housing is still serviceable and only the internal wear parts need replacement.\u003c\/p\u003e\u003cp\u003eSierra manufactures this kit to meet or exceed original equipment quality, giving outboard owners a reliable alternative to sourcing individual OEM parts. It is built to be a direct fit for the Johnson\/Evinrude applications it replaces, using the same interface dimensions as the original equipment part numbers it supersedes.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-3401\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit, Without Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Impeller, Sierra 18-3051 (O.E. #395289), Qty. 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.47 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude Outboard Motor\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e395271\u003c\/li\u003e\n\u003cli\u003e394394\u003c\/li\u003e\n\u003cli\u003e0395270\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Sierra 18-3401 Water Pump Kit?\u003c\/strong\u003e The kit includes a Sierra 18-3051 impeller (O.E. #395289, qty. 1).
