Description
SIERRA Mercury Water Pump Impeller – 18-3012
Water-pump impeller for older Mercury outboard water pumps using OEM 47-22748. Sierra designs the replacement around the specified OEM pump geometry and interchange references.
- Application: older Mercury outboard water pumps using OEM 47-22748
- 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: Mercury Marine: 47-22748
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.
