This Jabsco flexible impeller (Profile D, part 4528-0003-P) fits most makes and models of bronze flexible impeller pumps used for engine cooling, bilge, transfer, and general purpose duties. Jabsco impellers go through rigorous quality checks for reliable, long-lasting performance.

Choosing the Right Impeller

Neoprene impellers are used for engine cooling and for fresh or salt water transfer, and are suitable where only small amounts of oil or diesel fuel are present. Nitrile impellers are used for bilge pumping and transfer duties where water is heavily contaminated, such as by oil or diesel.

Replacement and Maintenance

Replace impellers at least once a year, or sooner depending on engine duty. To remove an impeller, take off the end cover screws and use a Jabsco Impeller Removal Tool or channel lock pliers on the hub — avoid screwdrivers, which can damage the pump body and cause leaks. Always carry a spare impeller on board, and grease new impellers before installing them to ease fitting and protect against initial prime.
