The water pump is the heart of your MerCruiser sterndrive cooling system; if it is not functioning at full capacity, there is a risk of overheating the engine. Each Sierra pump is engineered to meet or exceed factory specifications and is matched to the GM block used for many MerCruiser engines. These bi-directional marine water pumps feature a cast iron body and stainless steel shaft to stand up to the marine environment. Sierra water pumps are made from new castings and are not remanufactured. Give your cooling system a fresh start with a Sierra replacement water pump.
