Complete Your Purchase
Great for seasonal maintenance and to have as a spare for unexpected failures.
Impellers are the heart of an engine’s cooling system. Running through silty or sandy water or running a pump dry can quickly ruin an impeller and cause the engine to overheat. Regular inspection and replacement of the impeller is recommended and will keep your Mercury outboard’s cooling system running in top form. Every Sierra impeller is engineered to meet or exceed manufacturer’s specifications to give boaters and technicians the confidence of the proper fit and function. Having a spare is an excellent way to save the day in the event of an unexpected failure.
