Pump kits simplify gathering parts to rebuild water pumps. Outboards rely on the water pump to maintain safe operating temperatures. Regular service maintains proper water flow and can prevent overheating the engine. Sierra makes servicing Johnson/Evinrude outboard water pumps easier by packaging all the necessary parts in a single kit. Each component in the kit is engineered to meet or exceed manufacturers specifications. Sierra service kits eliminate the time spent researching and sourcing individual parts, so that you can focus on servicing the water pump and getting back on the water.
