Engine / Belt Driven Watermakers are ideally suited where the propulsion engine runs more than once a week. They produce 21 – 64 gallons of fresh water per hour, even on the smallest yacht without a generator. Every time the diesel engine runs, you will produce large quantities of fresh water and charge your batteries at the same time. Adding a watermaker pump to the alternator’s load will also benefit your diesel engine, as it does not like to run underloaded. 
The high-pressure pump mounts on a custom bracket directly to the main engine or generator. An electromagnetic clutch, driven via one A section belt couples the watermakers’ pump to the engine. The supplied U-bracket helps to install the pump on the engine like a second alternator.
