Complete Your Purchase
Keep your Yamaha at peak performance by running at the optimum temperature.
Outboards rely on the water pump to maintain optimum operating temperatures. Any restriction to the water flow can result in a loss of power and efficiency and possibly overheating the engine.
Sierra makes sourcing the parts to service a Yamaha outboard water pump easy. By packaging all the necessary parts in a single kit, extra time spent sourcing each individual part is eliminated. Sierra engineers each component included in the kit to meet or exceed manufacturer specifications. Boaters and technicians can be assured a Sierra part will fit right the first time and restore function to factory standards or better.
