Water-pump impeller for OMC Cobra/sterndrive applications using OEM 983895 / 777128; many documented applications are 1986-1993 and engine-specific. Sierra designs the replacement around the specified OEM pump geometry and interchange references.

• Application: OMC Cobra/sterndrive applications using OEM 983895 / 777128; many documented applications are 1986-1993 and engine-specific
• Function: Circulates raw cooling water through the engine cooling system; a worn, hardened or damaged impeller can reduce water flow and cause overheating.

• Blade count: 10
• Interchange: GLM: 89950; Mallory: 9-45280; OMC Stern Drive: 777128, 983895

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.
