Keeping your boat's cooling system primed is essential, and this kit provides a straightforward replacement to maintain efficiency. The durable neoprene blades deliver flexible pumping performance under demanding marine conditions, while the plastic insert and Double Flat Drive support broad compatibility across bronze flexible impeller systems. For best results, replace annually or sooner depending on duty cycle, and grease new impellers to ease installation and protect during priming. The removal process is simple: remove end cover screws and grip the hub with a Jabsco Impeller Removal Tool or channel-lock pliers (avoid screwdrivers to prevent damage and leaks). Carry spare impellers on board for quick preventative maintenance and reduced downtime. After replacing the gasket and end cover, test the pump to ensure a secure seal and proper operation. Refer to your pump’s manual for exact procedures and torque specs.
