Q: How often should I replace the water pump impeller?
A: As a crucial part of preventative maintenance, we recommend inspecting the impeller annually and replacing it every 1-2 years or every 100-200 hours of use. Replacement frequency should be increased if operating in saltwater or debris-heavy water.
