Common Concerns Answered
How often should an impeller be replaced?
Impellers should be inspected annually and replaced every 1-2 years or at the first sign of wear, cracking, or stiffness, depending on operating hours and environmental conditions.
Can a worn impeller cause engine overheating?
Yes, a worn or damaged impeller cannot move sufficient raw water through the cooling system, leading to reduced heat exchange and potential engine overheating.
Will this impeller kit fit my specific pump model?
This DOMETIC M18-3287 impeller kit is designed for specific DOMETIC raw water pump models. Always verify your pump's model number against the compatibility list provided by the pump manufacturer before purchase.
