A functioning impeller is critical for circulating water through the cooling passages to prevent powerhead damage. This replacement part is made from high-quality neoprene for maximum durability and flexibility, ensuring reliable water pressure even at low idle speeds. It is a direct-fit replacement for several original equipment part numbers, making it an essential part of your routine maintenance kit.

Additional Information
NOTE: Small outboards are particularly sensitive to cooling issues caused by salt buildup or debris. When installing a new impeller, we recommend flushing the water tubes and inspecting the impeller drive key for wear. If your water pump housing is scored or heat-damaged, a complete pump repair kit should be used to ensure proper cooling.
