Jabsco Impeller Kit - 10 Blade - Neoprene - 2-¼"

The Jabsco Impeller Kit - 10 Blade - Neoprene - 2-¼" is an essential replacement component for marine and automotive cooling systems that rely on positive displacement pump circulation. This impeller serves as the heart of raw-water cooling loops, delivering reliable fluid transfer in engines equipped with Jabsco circulation pumps. Whether you're managing routine maintenance on a diesel inboard, gasoline marine engine, or auxiliary cooling circuit, having a quality replacement impeller on hand prevents catastrophic overheating and extends engine life significantly.

The 10-blade design with neoprene construction delivers consistent pump performance across varying water temperatures and salinity levels common in marine environments. Neoprene's elasticity and resistance to oil, coolant, and salt water make it the preferred elastomer for wet-end impeller applications where synthetic rubber won't degrade under continuous immersion. The 2-¼" diameter accommodates mid-range displacement pumps, ensuring adequate volumetric flow while maintaining pressure characteristics designed by Jabsco's engineering. This specific blade geometry minimizes cavitation and noise while maximizing prime-mover efficiency—critical for fuel economy and long-term seal integrity in auxiliary cooling systems.

Mechanics and boatyard technicians rely on the Jabsco Impeller Kit - 10 Blade - Neoprene - 2-¼" for preventive maintenance schedules and emergency repairs on standard marine cooling installations. Replacement is straightforward—typically requiring only pump disassembly and impeller seat cleaning—making this a practical DIY service for owners comfortable with basic mechanical work. Verify pump model compatibility before ordering, as Jabsco manufactures multiple impeller sizes for their full pump range. Store spare impellers in a cool, dry location to preserve neoprene flexibility and ensure immediate availability when unexpected cooling system issues arise during the season.
