SIERRA Johnson/Evinrude Water Pump Impeller – 18-3006

Water-pump impeller for Johnson/Evinrude outboards using OEM 378891 / 775521. Sierra designs the replacement around the specified OEM pump geometry and interchange references.

• Application: Johnson/Evinrude outboards using OEM 378891 / 775521
• 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: 89480; Johnson/Evinrude Outboard: 378891, 775521; Mallory: 9-45217, 9-45222

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.
