Flexible Impeller 51 mm 6303-0003 09-824P for Jabsco Johnson Yanmar Oberdorfer Pump with O-Ring — Germany Local Warehouse
Product Overview
Flexible impeller kit, 6 blades, 51 mm diameter, 22 mm wide, 8 mm shaft bore, supplied with the cover O-ring. It replaces Jabsco 6303-0003 pumps, Johnson 09-824P pumps, Yanmar 124223-42092 seawater pumps and Oberdorfer 7482 pumps, and crosses to Sierra 18-30005, Vetus IMP00101, CEF 500210 and Milwaukee 49-16-2771. The impeller is H-157. Shipped from our Germany local warehouse.
These pumps are everywhere on inland water: engine raw water, washdown, toilet, bilge transfer. The impeller is the only part that is expected to fail on a schedule, and on a boat that is lifted for winter the winter is when it should be done, not in April.
Frost is the other factor. A pump left full of water through a hard winter can crack the body, and an impeller that sat squeezed against the cam all winter takes a set that no amount of running brings back. The blades stay bent, the flow never returns, and the cover O-ring has usually hardened by the same point.
