Ensure your vintage outboard maintains proper operating temperatures with this New Outboard Water Pump Impeller manufactured by EMP. This professional-grade cooling component is specifically designed for Johnson and Evinrude 2-cylinder engines produced between 1964 and 1973, covering the popular 9.5 HP and 10 HP models.
The impeller is a critical maintenance part responsible for circulating water through the engine block to prevent overheating and powerhead damage.

Additional Information
NOTE: For vintage outboards, the water pump is the heart of the engine's longevity. We recommend replacing the impeller every season or every 100 hours to prevent hardening and blade failure. During installation, inspect the water pump cup and wear plate for any signs of heat distortion or deep scoring; a smooth surface is essential for the impeller to create the vacuum required for effective cooling.
