Frequently Asked Questions
Q: How often should I replace my marine impeller?
A: Replace every season or 100 hours of use. Impellers degrade over time even if the boat isn’t used frequently.
Q: What’s the difference between a raw water pump and a circulation pump?
A: A raw water pump draws external water for cooling, while a circulation pump moves coolant inside closed systems.
Q: How can I tell if my cooling pump is failing?
A: Watch for engine overheating, reduced water flow, squealing noises, or visible leaks from the pump housing.
