Hydraulic steering systems are now being used in every category of small vessel. In many ways, hydraulic steering is preferable to mechanical steering. Hydraulic systems normally consist of two main components, steering cylinder(s) and a steering wheel pump. The steering wheel pump can be either a plunger pump or a gear pump. Whichever type is installed, steering is achieved by turning the steering wheel in either direction causing oil from the wheel pump to be supplied to the appropriate side of the cylinder. Oil is returned back to the pump via the opposite side of the cylinder.

The linear motion of the cylinder rod is transformed to a rotary motion by the tiller, which turns the rudder shaft and rudder. Check valves (non-return valves) are usually incorporated to prevent the rudder driving the steering wheel pump. If an autopilot is to be included in such a hydraulic steering system, then the oil flow providing the rudder movement must be controlled by electrical signals from the autopilot.

Simrad develops powerful drive units based on long experience from the rough conditions in the North Atlantic Ocean as well as the high humidity and high temperatures in Florida and other tropical areas. They drive the rudder with precision and endurance through the toughest conditions and on the longest crossings. Several models are available to fit the various types and sizes of boat and steering systems. The Simrad range of reversible hydraulic pumps is easily adaptable to the boat"s hydraulic hand steering system and allows the autopilot to have smooth and precise control.ModelVOLTSAutopilot ComputerRAM CapacityFlow Rate At 10 barMax Pressure barPWR ConsumptionBoat Length
