The kit is built from aluminum and plastic components and includes the gaskets and impeller needed to restore proper cooling system operation during a water pump rebuild. It is designed as a direct cross-reference to Yamaha water pump repair kits, making it a straightforward replacement when servicing the lower unit cooling assembly.\u003c\/p\u003e\u003cp\u003eThis kit is the same as Sierra 18-3371 but does not include the water pump housing, so it is intended for applications where the existing housing is being reused and only the internal wear components need replacement. Included in the kit are the 18-0239 water pump gasket (replacing O.E. 688-44315-A0-00), the 18-0240 water pump gasket (replacing O.E. 688-44316-A0-00), and the 18-3070 impeller, along with the impeller key and O-ring needed for a complete rebuild. Replacing these components at the recommended service interval helps prevent impeller wear from causing loss of water flow and overheating.\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 18-3370\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Without Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum, Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.63 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999753519\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e 18-0239 Water Pump Gasket, 18-0240 Water Pump Gasket, 18-3070 Impeller\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis kit is a cross-reference replacement for Yamaha water pump repair kits bearing part numbers 692-W0078-00-00, 692-W0078-01-00, and 692-W0078-A0-00.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e692-W0078-00-00\u003c\/li\u003e\n\u003cli\u003e692-W0078-01-00\u003c\/li\u003e\n\u003cli\u003e692-W0078-A0-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3370 water pump kit include?\u003c\/strong\u003e The kit includes the 18-0239 water pump gasket, the 18-0240 water pump gasket, and the 18-3070 impeller, without a water pump housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3370 kit come with a water pump housing?\u003c\/strong\u003e No. The 18-3370 is the same kit as Sierra 18-3371 but does not contain the water pump housing, so the existing housing must be reused.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the Sierra 18-3370 replace?\u003c\/strong\u003e It replaces Yamaha part numbers 692-W0078-00-00, 692-W0078-01-00, and 692-W0078-A0-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the 18-0239 gasket used for in this kit?\u003c\/strong\u003e The 18-0239 water pump gasket in the 18-3370 kit replaces O.E.
