Let Sierra do the leg-work gathering parts. Outboards rely on the water pump to maintain safe operating temperatures. Regular service can maintain proper water flow and prevent overheating the engine. Sierra makes servicing Yamaha outboard water pumps a little easier by packaging all the necessary parts in a single kit. Each component in the kit is engineered to meet or exceed Yamaha specifications. Sierra service kits eliminate the time spent researching and sourcing individual parts, so that you can focus servicing the water pump and getting back on the water.
