CEF Impeller – Replacement Impeller for Cummins & Sherwood Seawater Pumps

When the impeller has done its job, every hour counts until the next season. This CEF impeller is the right replacement for Cummins and Sherwood raw water pumps – ensuring your engine reliably stays at operating temperature.

Tip: Replace the impeller at least once per season or every 200 operating hours – always completely remove old impeller fragments from the pump and cooling circuit before installing the new impeller. When installing, lightly lubricate the vanes with acid-free Vaseline or glycerin.
