Installation notes: Replacing an impeller is straightforward: remove end cover screws, grip the hub with a Jabsco Impeller Removal Tool or channel-lock pliers, and install a new impeller. Do not use screwdrivers; grease new impellers to ease installation and provide initial protection during priming. Recheck the gasket and end cover before bringing the pump back online. Carry spare impellers on board for emergencies—your engine cooling system depends on it.
This kit is designed to deliver dependable performance for engine cooling and pump operations. By maintaining a proper replacement schedule and following the recommended installation steps, you can help ensure reliable prime, steady flow, and reduced downtime in your cooling, bilge, and transfer applications.
