Mercruiser Impeller GM SIE18-3087

For use with either Quicksilver, Model 46-72774-A32 pump or the Jabsco replacement.

Most inboard boats use a raw water system to cool the engine. Cold water cycles through the engine 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.

Overall impellers tend to be durable. During operation, water keeps them lubricated and prevents from damage. 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 should pay close attention to the condition of your impeller. Regular inspections and replacements can prevent major headaches and expenses down the road. 

We recomend keeping a spare new impeller in your boat just in case.
