Avoid Engine Damage Due to a Bad Impeller WHAT DO IMPELLERS DO?
Impellers pump cold water into your boat’s engine to cool it down while in use. If you have a bad impeller it can cause big problems.

How do Impellers become Damaged?
Your boat’s impeller is a series of rubber vanes molded around a hub. The tips of these flexible vanes can wear out for many reasons due to simple use or if the boat is in sandy water. Abrasive sandlike material can cause the impeller to wear out faster.
Impellers can also wear out by becoming stiff and brittle due to the motor sitting unused for several seasons or being exposed to heat. Water lubricates the impeller, and if it’s run dry, the impeller can be ruined in a few seconds.
