A key component of the pump assembly is the rubber impeller, which spins inside the lower unit to provide the suction and pressure needed to supply water. Impeller is a major part of the engines seawater system which cools the secondary internal fresh water system which in turn cools the engine. The impeller is made up of several flexible blades and designed to move a fluid by rotation.
Product Description
Over time, the rubber can deteriorate and lose its elasticity, leading to a loss of cooling-water pressure, and small pieces of the impeller can break off and be sucked into the cooling system. Internal gaskets, rings and seals can also break down, allowing water to escape inside the engine housing and, again, causing a loss of pressure. At this time, need to replace impeller. Wendong offers high quality water pump impeller replacement.
