Know that the water pump impeller

Know that the water pump impeller is one of more vulnerable components of your pump assembly. The impeller needs to be serviced once a year or every 100 hours, by a marine technician, and replaced as needed. Impellers are a series of rubber vanes that are molded around a hub which rotates. Friction, corrosion, water, sand, disuse and heat can all abraid and degrade the rubber. When the vanes are bent, this is also an indication that replacement is required.
