Unlike the Sierra 18-3372 kit, which is sold without a housing, the 18-3373 includes the water pump housing along with the internal wear components needed to restore cooling system performance. The kit is built around aluminum construction for the housing and related parts, giving it the durability needed for continuous exposure to raw water cooling flow.\u003c\/p\u003e\u003cp\u003eInside the kit, buyers get the water pump gasket (Sierra part 18-0244, OEM equivalent 6E5-44315-A0-00), four mounting bolts (Sierra part 18-0256, OEM equivalent 97095-08045-00), and the impeller (Sierra part 18-3071) that does the actual work of pumping cooling water through the outboard. Supplying the housing along with these wear parts in one kit means the water pump can be rebuilt or replaced in a single job rather than sourcing the housing separately.\u003c\/p\u003e\u003cp\u003eThe Sierra 18-3373 is a direct replacement for Yamaha OEM part number 6E5-W0078-A1-00, and it is engineered to meet or exceed the performance of the original equipment part it replaces.\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 18-3373\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit with Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yamaha Outboard Motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Includes:\u003c\/strong\u003e Water Pump Housing, Gasket (18-0244), Bolts Qty 4 (18-0256), Impeller (18-3071)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket OEM Equivalent:\u003c\/strong\u003e 6E5-44315-A0-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt OEM Equivalent:\u003c\/strong\u003e 97095-08045-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999755865\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha Outboard Motor\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e6E5-W0078-A1-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-3373 kit include the water pump housing?\u003c\/strong\u003e Yes, the 18-3373 kit includes the water pump housing.
