Installation and Maintenance

Replacing the impeller is a standard maintenance procedure that prevents engine overheating. We recommend replacement every season or after 300 hours of operation, even if the impeller appears to be in good condition. The old element may be damaged internally, which affects pump performance. Before installation, ensure that the pump chamber is clean and the seals are not damaged. The new SIERRA 118-3058 impeller is characterized by high resistance to abrasion and seawater action.
