If installed correctly an impeller can last several years but it is always advisable to keep a schedule rather than remedial maintenance.Replacing impellers is quite simple. By removing the end cover screws it is possible to remove the impeller by using either a Jabsco Impeller Removal Tool, or locking pliers, to grip the hub of the impeller. Don?t use screwdrivers as they can damage the front of the pump body, causing leaks, and they can be dangerous in confined spaces.Always carry spare impellers on board in case of emergency. The turbine is one of the most important components of the engine cooling system and should always be treated as such. Always grease new impellers. Firstly, it makes it easier to install the impeller into the pump bore, and secondly it provides additional protection to the impeller prime. After replacing the seal and end cover the pump is immediately ready for use.
