Jabsco 17370-0001-P Water Pump Impeller, Replaces Cummins 3008503, CAT 3N-4859, DDA 8927570

The Jabsco 17370-0001-P is a neoprene water pump impeller built as a direct replacement for the original engine-driven raw water pump impeller on applicable Cummins, CAT, and DDA (Detroit Diesel Allison) engines. Neoprene construction gives the impeller a long working life under continuous marine raw-water pumping duty, resisting wear from the twisting and flexing that occurs every time the pump rotates. The impeller uses a double flat drive type and mounts on a 1 inch shaft, with 12 blades on a 3-3/4 inch diameter body and a 3-1/2 inch width.

Each 17370-0001-P kit ships complete with lubricant, a replacement gasket, and installation instructions, so the job can be finished in one sitting without sourcing additional parts. Installation follows a standard impeller service procedure: remove the end cover screws, endcover, and old gasket, extract the worn impeller with a Jabsco removal tool, clear any debris from the pump chamber, lubricate the pump wall, then insert the new impeller with a twisting motion, fit the new gasket and endcover, and tighten down. This impeller directly replaces Cummins 3008503, CAT 3N-4859, and DDA 8927570, making it a straightforward swap for engines currently fitted with any of those OEM part numbers.
