The impeller compound is formulated based on the size and application of the pump it serves, and the remaining kit components are constructed to meet or exceed original equipment manufacturer specifications, giving boat owners a reliable replacement option when a water pump impeller wears out or fails. Impellers are a wear item that should be inspected and replaced on a regular service interval, since a cracked, worn, or brittle impeller can restrict raw water flow to the engine and lead to overheating. This kit is assembled to Sierra's quality standards and packaged as a complete kit rather than a standalone impeller, so the components needed for a proper water pump service are included together. It is intended for Volvo Penta applications and cross-references directly to Volvo Penta OEM part number 21213660, making it a straightforward replacement for that OE number.\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 18-3276-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Impeller Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Italy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 11.2 cm H x 6.6 cm L x 6.9 cm W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.28 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282292218\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Volvo Penta Water Pumps \u0026amp; Impellers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eVolvo Penta\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e21213660\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3276-1 impeller kit fit?\u003c\/strong\u003e The Sierra 18-3276-1 is designed for Volvo Penta marine engine water pumps and cross-references directly to Volvo Penta OEM part number 21213660.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-3276-1 the same as Volvo Penta part 21213660?\u003c\/strong\u003e Yes, Sierra impeller kit 18-3276-1 replaces Volvo Penta OEM part number 21213660.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the 18-3276-1 kit?\u003c\/strong\u003e This kit includes the impeller along with the other components needed to complete a water pump impeller service, packaged together as a single unit count kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this impeller kit weigh?\u003c\/strong\u003e The Sierra 18-3276-1 impeller kit weighs 0.28 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of the 18-3276-1 kit?\u003c\/strong\u003e The kit ships in packaging measuring 11.2 cm H x 6.6 cm L x 6.9 cm W.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is the Sierra 18-3276-1 impeller kit made?\u003c\/strong\u003e The country of origin for this impeller kit is Italy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the impeller need to be replaced periodically?\u003c\/strong\u003e A water pump impeller like the one in kit 18-3276-1 wears over time, and a worn, cracked, or brittle impeller can restrict raw water flow and cause engine overheating, so periodic replacement is recommended as part of routine maintenance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra impeller compound the same for every application?\u003c\/strong\u003e No, Sierra formulates the impeller compound in the 18-3276-1 kit based on the specific size and application of the water pump it is designed for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre the components in this kit built to OEM standards?\u003c\/strong\u003e Yes, the components in the Sierra 18-3276-1 kit are constructed to meet or exceed original equipment manufacturer specifications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-3276-1 impeller kit?\u003c\/strong\u003e The UPC for this Volvo Penta impeller kit is 808282292218.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this kit work for outboard, inboard, and sterndrive engines?\u003c\/strong\u003e Sierra offers impeller kits across outboard, inboard, and sterndrive applications, and the 18-3276-1 kit is the version designated for Volvo Penta engines with OEM equivalent 21213660.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988142600411,"sku":"SIE-18-3276-1","price":46.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/Untitled-1__86580.1771793486.500.750.jpg?v=1785188137","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3276-1-water-pump-impeller-kit-for-volvo-penta-1999-and-later-replaces-oem-3862567-and-21213660","provider":"Good Vibes Marina","version":"1.0","type":"link"}
