Marine Engine Impellers

Marine engine impellers are a critical component of a boat's raw-water cooling system, circulating cooling water through the engine and heat exchanger to help maintain proper operating temperatures. A damaged, worn, or improperly functioning impeller can reduce water flow and contribute to engine overheating.

Because flexible rubber impellers can be damaged when operated without adequate water lubrication, regular inspection and preventative replacement are essential parts of marine engine maintenance. Boaters should also consider carrying a replacement impeller and the necessary tools onboard for emergency repairs.
