18-3091 Impeller
Complete Your Purchase
Replacement impeller for smaller Johnson/Evinrude outboards.
Impellers are the heart of an engine’s cooling system. Running through silty or sandy water or running a pump dry can ruin an impeller quickly and cause the engine to overheat. Sierra offers replacement impellers engineered to meet or exceed manufacturer’s specifications. Boaters and technicians can have the confidence of a factory fit and function when using a Sierra impeller. Having a spare for unexpected failures can save the day.
Key Features
- Impeller is engineered to meet OEM specifications
- Compatible with older 4hp—8hp Johnson/Evinrude outboards
