Sierra impellers meet or exceed Yamaha and Mercury requirements, ensuring OEM fit and function for boaters and technicians. These neoprene impellers are suitable with many Mercury and Yamaha outboards ranging from 4 to 6 horsepower. Because unexpected breakdowns sometimes happen, having a spare impeller on board is essential in the event of an emergency. Under typical operating conditions, impellers are the core of an engine's cooling system and must be checked and replaced regularly. Running a pump dry or through silty or sandy water can quickly destroy an impeller and cause the engine to overheat. It's critical to keep an eye on cooling water output and replace the impeller if there's a drop inflow.
