Start the season off right with a fresh water pump Water pump impellers are one of the few parts that benefit from use. When an engine sits idle for the winter months, the impeller dries out and the vanes lose their elasticity and take a set.” This can lead to reduced water flow and engine overheating. Sierra impeller repair kits make the task of servicing the water pump easy. Each kit includes an impeller, impeller key, gaskets and O-rings to return the water pump to ship-shape and saves you the hassle of searching and sourcing each individual part. Starting the season off right by servicing the water pump on your Johnson/Evinrude, will pay dividends when the sun is out and the fish are biting.
