Rigorous quality processes are applied to Jabsco flexible impellers to ensure reliable, efficient, and long-lasting performance. It is recommended to replace all impellers at least once a year, or more frequently, depending on the engine's duty cycle. When the installation is correct, an impeller may last for several years, but it is always advisable to implement a schedule of preventative, rather than corrective, maintenance.

Replacing Jabsco impellers is a straightforward process. By removing the end cover screws, the impeller can be extracted using either a Jabsco Impeller Removal Tool or channel lock pliers to grip the impeller hub. Screwdrivers should be avoided as they may damage the pump body, causing leaks, and can be hazardous in confined spaces.

It is important to always carry spare impellers on board in case of emergencies, as the impeller is a vital component of the engine cooling system. New impellers should always be greased, as this facilitates the installation process and provides additional protection to the impeller during the initial priming phase. After replacing the gasket and end cover, the MPN for this impeller is 836-0001-P.

In summary, Jabsco flexible impellers are designed to provide reliable and efficient performance in a variety of pump applications. Proper maintenance, including regular replacement, is essential to ensure the long-term functionality of the engine cooling system and other critical components.
