How to Repair a Kingfisher 9.9 Outboard Motor's Water Pump

The Kingfisher 9.9 is an outboard boat motor designed for smaller watercraft. The water pump on the motor circulates water through the engine and keeps it from overheating. A bad water pump can leave you dead in the water. Fortunately, water pump replacement kits are available at marine auto shops. Installing your own outboard water pump does not require a lot of mechanical know-how. It takes approximately one to to hours to replace the water pump in the Kingfisher outboard motor.
