Impellers circulate cold water within the engine of your boat to keep it cool while it is running. Physical wear and tear, such as cracks in the impeller vane roots and melted or damaged vanes, all point to a defective boat impeller. The boat engine overheats when you accelerate. The impeller vanes also lose flexibility. Outboard motors use a water pump to maintain acceptable operating temperatures, and routine maintenance keeps the engine cool and guards against overheating. By assembling all parts into a single kit, Sierra makes maintenance of Johnson/Evinrude outboard water pumps simple. The kit's parts go above and beyond what the maker intended. An all-in-one kit allows you to focus on maintaining the water pump and going out on the water by eliminating the need to find and study individual parts.
