If you run a Cummins-powered workboat, fishing vessel or cruising yacht, this is likely the impeller you need.\u003cbr\u003e\u003cbr\u003eThe impeller is the engine's first line of defence against overheating — it draws raw water through the hull fitting and circulates it through the heat exchanger or keel cooling circuit. Neoprene blades gradually lose elasticity with use and heat cycles, reducing flow before failure becomes obvious. Annual replacement is strongly recommended, and carrying a spare on board is simply good seamanship.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e•    Outside diameter: 65mm\u003cbr\u003e•    Length: 51mm\u003cbr\u003e•    Shaft bore: 16mm (⅝\" keyed drive)\u003cbr\u003e•    Blades: 12\u003cbr\u003e•    Material: Neoprene\u003cbr\u003e•    Supplied with: gasket\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCompatible Sherwood pump models\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eG151 · G155 · G157 · G1503 · G1503-01 · G1503-03 · GC1 · GC1-01 · GC4 · GC4-01 · GC5 · GC5-01 · P151 · P1505 · P1505-01\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTypical engine applications\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e•    Cummins 4B series (250HP) — Cummins 3349340 \/ 3349198 \/ 3393854\u003cbr\u003e•    Cummins 6B series (250HP) — Cummins 3912962 \/ 3916720 \/ 3920298 \/ 3927684\u003cbr\u003e•    Mercruiser 7.3 diesel (L\/270)\u003cbr\u003e•    Marine Power inboard engines\u003cbr\u003e•    StarPower inboard and stern drive models\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eOEM \/ cross-reference part numbers\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eSherwood 15000K · Jabsco 18327-0001 · Cummins 3349198 \/ 3349340 \/ 3916720 · Mercruiser 47-453126 \/ 47-853126 · JMP 7352-01 · DJ Pump 08-36-1201 · CEF 500167\u003cbr\u003e\u003c\/p\u003e","brand":"Boat Fittings","offers":[{"title":"Default Title","offer_id":57299450560887,"sku":null,"price":39.37,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/5679\/9306\/files\/SM-2197-2.jpg?v=1783940040","url":"https:\/\/www.boatfittings.co.uk\/products\/osculati-16-194-42-replacement-impeller-cef-167","provider":"Boat Fittings","version":"1.0","type":"link"}
