Additional Information
NOTE: Even on small horsepower engines, cooling system failure can lead to significant powerhead damage. We recommend checking the water pump's "tell-tale" stream every time you start the motor. During installation, inspect the pump cup and wear plate for any grooves or heat-related melting. If these surfaces are not smooth, a complete water pump repair kit may be necessary to maintain proper pressure.
