Jabsco Impeller Kit - 10 Blade - Nitrile - 1-19/32" Diameter

The Jabsco Impeller Kit - 10 Blade - Nitrile - 1-19/32" Diameter is a critical replacement component for marine and automotive cooling systems that rely on positive displacement pump technology. As a mechanic, you know that impellers are the working heart of any seawater or freshwater cooling circulation system—they move coolant through engine blocks and heat exchangers to prevent thermal runaway. This Jabsco impeller kit addresses wear, cavitation damage, and performance loss in bilge pumps, engine cooling loops, and auxiliary systems where original equipment has degraded.

Built from nitrile elastomer, this 10-blade impeller delivers superior resistance to seawater corrosion, fuel contamination, and temperature cycling compared to older rubber compounds. The 1-19/32" diameter and single flat drive design integrate seamlessly into Jabsco pump housings, while the 3/4" shaft diameter and 5/16" shaft width ensure positive engagement without slippage under load. The brass insert provides structural integrity and prevents shaft wear, a critical detail that extends service life in high-cycle applications. Nitrile's elasticity allows the flexible blade design to maintain seal contact against the pump housing during operation, maximizing flow rate and pressure consistency across varying RPM ranges.

Technicians servicing inboard marine engines, RV heating systems, and automotive auxiliary cooling loops benefit most from keeping this impeller kit on hand for preventive maintenance or emergency repairs. Whether you're rebuilding a Jabsco raw-water pump or replacing a worn impeller that's causing cavitation noise and reduced coolant flow, this OEM-spec replacement restores original performance without requiring housing modification. Verify your pump's drive type and shaft dimensions against the single flat drive configuration before ordering to ensure compatibility with your specific application.
