Most inboardboats usea raw water system to cool the engine. Cold water cyclesthrough theengine at a safe operating temperature. Boats use impellers to take in raw water. An impeller is a hub with flexible rubber fins. When the impeller rotates, water is sucked into the cooling system.
Overallimpellers tend to be durable. During operation, water keeps them lubricated and prevents fromdamage. That being said, the potential engine damage from a failed impeller is substantial. Without the impeller, your boat’s engine will overheat.
As a boat owner, you shouldpay closeattention to the condition of your impeller. Regularinspections and replacements can prevent major headaches and expenses down the road.
We recomendkeeping a sparenew impeller in your boat just in case.
