Maintenance and lifespan

Replace all impellers at least once every year, or sooner if your engine duty demands it. With proper installation, an impeller can last for several years, but sticking to a preventative maintenance schedule minimizes unexpected failures.

Installation and replacement tips

• Ease of replacement: Remove the end cover screws, then use a Jabsco Impeller Removal Tool or channel‑lock pliers to grip the impeller hub. Avoid screwdrivers, which can damage the pump face or cause hazards in confined spaces.
• Spare parts on hand: Always carry spare impellers on board for emergencies.
• Installation aid: Grease new impellers before installation to ease fitting into the pump bore and to protect the impeller during initial prime.
• Reassembly: After replacing the gasket and end cover, the pump is ready to use once reassembled.
