Sierra 18-3570Click To Copy 18-3570 Water Pump Kit for Mercury/Mariner Outboard Motors

Restore a Mercury outboard water pump to ship-shape with a complete service kit Starting the season with a freshly serviced water pump will pay dividends later when the sun is out and the fish are biting. Water pump impellers benefit from use and can dry out and lose their elasticity during the winter months when outboards sit idle. Boaters fortunate enough to have a year-long season can wear out impellers and are advised to service the water pump once a year or every 100 hours. If left alone both situations can lead to reduced water flow in the cooling system that can result in overheating the engine. Sierra water pump kits are designed and packaged to make service simple. Each kit includes everything needed to restore the water pump and eliminates the hassle of searching for and sourcing the individual parts. Invest early in this year s boating season by servicing the water pump and capitalize on your time spent on the water. For 50 years Sierra has been producing parts engineered to meet or exceed the specifications of marine engine manufacturers and has gained the confidence of engine manufacturers and boat builders to a point of supplying them with OEM parts. Boaters and technicians can be assured a Sierra part will fit right the first time and restore function to OEM specifications.
