Harken offers four sizes of hydraulic power units. Hydro 2 and Hydro 4 are single-motor power units while Hydro 6 and Hydro 8 use dual motors that are capable of very high flow rates and provide a backup power source. Hydro 2 is used on boats to 45' (13.7 m) that require two or three functions. Hydro 2 is offered for either 12- or 24-volt installations. Larger units are offered only for use with 24 volts.The units come with a control box that turns on the motors and interfaces with the switches to open and close the valves for each piece of equipment.
