Installation and Maintenance Tips

Replacing the impeller is a task that should not be overlooked. We recommend performing this every season or after 300-500 hours of operation, even if the pump shows no visible damage. A worn impeller can cause a drop in water pressure, leading to engine overheating and serious mechanical damage. During installation, ensure that seals are clean and the new element is properly seated in the pump housing. Regular cooling system maintenance extends engine life and ensures safety on the water.
