The impeller is the wear component inside a generator's raw water pump that circulates cooling water through the engine; over time the rubber vanes lose flexibility, crack, or shed material, leading to overheating and reduced cooling flow. Replacing the impeller kit at regular service intervals helps keep the generator's cooling system operating at proper capacity and helps prevent downstream damage to the heat exchanger or engine block.\u003c\/p\u003e\u003cp\u003eThis kit is built to Sierra's standard of meeting or exceeding the original equipment part it replaces, and is intended to withstand the harsh marine operating environment. It is suited for a wide range of Westerbeke generator models spanning both 50Hz and 60Hz configurations, making it a broadly applicable replacement part for owners servicing Westerbeke-powered generator sets. The kit ships as a compact, lightweight component for straightforward installation during routine maintenance.\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 223-3305\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Impeller Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Westerbeke Generator Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282288549\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00808282288549\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit Type:\u003c\/strong\u003e Universal Fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWesterbeke 32620 generator\u003c\/li\u003e\n\u003cli\u003eWesterbeke 3.0 WMD (60Hz) \/ 2.4 WMD (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 3.8\/4.2 BCDT (60Hz) \/ 3.5 BCDT (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 4.0 BCG (60Hz) \/ 3.0 BCG (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 4.5 BCG (60Hz) \/ 3.75 BCG (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 4.5 BCGB (60Hz) \/ 3.75 BCGB (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 4.5 BCGTC (60Hz) \/ 3.75 BCGB (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 6.5 BCG (60Hz) \/ 4.8 BCG (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 7.0 BCG (60Hz) \/ 5.0 BCG (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 7.0 BCGA (60Hz) \/ 5.0 BCGA (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 7.0 BCGB (60Hz) \/ 6.0 BCGB (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 7.2 BCGTC (60Hz) \/ 6.0 BCGTC (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 9.0 BTG (60Hz) \/ 7.0 BTG (50Hz)\u003c\/li\u003e\n\u003cli\u003eWesterbeke 9.6 BCGTC (60Hz) \/ 8.0 BCGTC (50Hz)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat generator does the Sierra 223-3305 impeller kit fit?\u003c\/strong\u003e This impeller kit fits the Westerbeke 32620 generator as well as a broad range of other Westerbeke generator models across both 50Hz and 60Hz configurations, such as the 3.0 WMD, 4.0 BCG, 6.5 BCG, 7.0 BTG, and 9.6 BCGTC series.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 223-3305 a universal fit part?\u003c\/strong\u003e Yes, Sierra lists the 223-3305 impeller kit as a universal fit item across its supported range of Westerbeke generator models rather than being restricted to a single model.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the impeller kit weigh?\u003c\/strong\u003e The Sierra 223-3305 impeller kit weighs 0.08 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Sierra 223-3305 kit?\u003c\/strong\u003e The kit includes the impeller component for the Westerbeke generator raw water pump identified by Sierra part number 223-3305.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace the impeller in my Westerbeke generator?\u003c\/strong\u003e Impellers are a wear item in raw water pumps;
