When This Part Needs Replacement
Replace when the engine has weak seawater discharge, overheating, missing or cracked impeller vanes, hardened rubber, pump noise, or after a dry-run event. Impellers are also commonly replaced during seasonal cooling system service.
Installation Notes
Inspect the pump cover, wear plate, cam, O-ring or gasket, and shaft seal area during replacement. Remove any broken vane pieces from downstream hoses, heat exchangers, or coolers before restarting the engine.

Parts Desk Insight
This impeller is tied to specific Yanmar 6LY and 8LV raw-water pump applications. Matching by engine model alone is helpful, but the safest check is the pump assembly or engine serial number because cooling pump configurations can vary.
