Product Details
✓FITMENT - For Volvo Penta 3.0L, 4.3L V6, 5.0L, 5.7L and 8.1L V8 gas engines and D3 diesel on the crankshaft-driven sea water pump, carbureted and fuel injected, plus Johnson F6B-9 pumps on Indmar, Yanmar, PCM and Marine Power engines.
✓REPLACES - Replaces Volvo Penta 21213664, 3842786, 21951354 and 21951352, superseded by current 22307636. Cross-brand: Johnson Pump 09-812B-1, Jabsco 13554-0001, Yanmar 119773-42600, Indmar S685007. Crosses Sierra 18-3306. Not genuine Volvo Penta.
✓BUILD - 12 flexible neoprene vanes on a brass spline-drive hub, 57 mm OD, 48.2 mm deep, 14.3 mm bore, 12-spline drive. One kit with impeller, cover gasket and O-rings. Wear plate, cover bolts and pump housing are not included.
✓FUNCTION - Lifts raw water through the sea water pump into the engine cooling circuit. Resolves weak or absent discharge stream, overheating at idle or low speed, and vanes cracked, glazed, hardened or set from dry storage.
✓BEFORE ORDERING - Deep 48.2 mm impeller on the long-bolt pump only, not the 31.6 mm short impeller 21213660 or 21951346 on earlier pumps. Match blade count, OD, depth and spline. D3 diesel needs the matching pump design.
