Jabsco Impeller Kit - 12 Blade - Neoprene - 3-¾" Diameter - Brass Insert - Spline Drive

The Jabsco Impeller Kit – 12 Blade – Neoprene – 3-¾" Diameter – Brass Insert – Spline Drive is an essential replacement component for marine cooling and circulation systems found on boats of all sizes. After years of running engines and live wells, the impeller is the first part to wear, and a failed or degraded unit will cripple water flow, overheat your engine, or leave your fish tank stagnant.

This OEM-spec Jabsco impeller restores full pump performance and is built with 12 precisely molded neoprene blades. It is engineered to withstand saltwater corrosion and prolonged freshwater exposure without cracking or losing flexibility. The 3-¾-inch diameter and brass insert hub ensure proper fit and engagement in Jabsco pump housings, while the spline drive coupling transfers power reliably without slipping under load.

This replacement kit is ideal for recreational anglers, commercial fishermen, and cruising boaters who run Jabsco self-priming or centrifugal pump systems. Installation is straightforward—no special tools required—and the compact 3-¾-inch diameter fits the standard Jabsco housing family used across countless marine engines and applications.
