Take a long 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 ruin an impeller quickly and cause the engine to overheat. Sierra engineers their replacement impellers to meet or exceed OEM specifications. Boaters and technicians can be assured that a Sierra impeller will fit right and restore function to manufacturer specifications. Having a spare for unexpected failures can save the day.
