Regular inspection and replacement of impellers keep your outboard in ship-shape
Impellers are the heart of an engine’s cooling system and require regular inspection and replacement under normal operating conditions. Running through silty or sandy water or running a pump dry can ruin an impeller quickly and cause the engine to overheat. It is important to monitor cooling water outflow and replace the impeller at the first signs of reduced outflow.
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. Because unexpected failures can happen, it is important to have a spare onboard to save the day.
