It is designed for engines that use a v-belt drive and a one-piece pump housing configuration, making it a direct fit for that engine family rather than a universal pump. This is a full pump assembly, so it installs in place of the original unit to restore proper raw water flow and keep engine temperatures in check.\u003c\/p\u003e\u003cp\u003eAs a raw water circulation component, this pump is a wear item that should be inspected and serviced periodically, since impeller wear and housing fatigue are common causes of overheating in marine engines. When the impeller inside the 18-3600 eventually wears out, Sierra part number 18-3237 is the matching impeller repair kit for this pump, so owners can rebuild rather than replace the full assembly at the first sign of reduced flow. The 18-3600 carries a limited warranty and is intended as a direct equivalent to the original engine manufacturer pump 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 18-3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Sea Water Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e V6 and V8 engines with v-belt and 1-piece pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Repair Kit:\u003c\/strong\u003e 18-3237 impeller repair kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 7.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282286507\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00808282286507\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eV6 and V8 engines with v-belt and 1-piece pump\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e46-807151A12\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3600 sea water pump replace?\u003c\/strong\u003e The 18-3600 is a direct replacement for OEM number 46-807151A12, so any engine that originally used that pump can be fitted with the Sierra 18-3600 instead.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the 18-3600 fit?\u003c\/strong\u003e This pump fits V6 and V8 engines that use a v-belt drive along with a one-piece pump housing design; it is not a universal fit across all V6\/V8 configurations.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3600 include the impeller?\u003c\/strong\u003e The 18-3600 is a complete sea water pump assembly.
