Boat and Marine Impellers

What is a Boat Engine Impeller?

A boat engine impeller, a crucial component of the water pump, plays a vital role in the cooling system of marine engines. This small, yet powerful rotating device draws seawater into the engine or heat exchanger, ensuring the engine operates within safe temperature limits. Without a functional boat impeller, the risk of overheating and subsequent engine damage escalates significantly.

Importance of Regular Impeller Maintenance

Marine impellers, including those for specific models like Johnson Pumps impellers and Jabsco pump impellers, are susceptible to hardening over time. This deterioration impairs their ability to effectively draw water, potentially leading to pump overheating and failure. Regular replacement of impellers is not just a maintenance routine but an important measure to extend the lifespan of boat engines and prevent costly repairs.

When choosing a boat engine impeller, you can consider things like:
Model number: The model number of your engine can help identify which type and size of impeller you need.
