Description
SIERRA Johnson/Evinrude Water Pump Impeller – 18-3055
Water-pump impeller for Johnson/Evinrude outboards using OEM 389589 / 777129. Sierra designs the replacement around the specified OEM pump geometry and interchange references.
- Application: Johnson/Evinrude outboards using OEM 389589 / 777129
- Function: Circulates raw cooling water through the engine cooling system; a worn, hardened or damaged impeller can reduce water flow and cause overheating.
- Component: Flexible water-pump impeller
- Blade count: 6
- Interchange: GLM: 89690; Johnson/Evinrude Outboard: 389589, 777129; Mallory: 9-45202
Verify the engine model, serial range, pump housing and original impeller number before installation. Inspect the housing, wear plate, key and gaskets at the same time; replace damaged companion parts rather than installing a new impeller into a worn pump.
