Hydraulic steering systems use a lightweight hydraulic hose to control the steering. This offers larger or high-powered vessels a smooth, lightweight feel when turning the steering wheel. With fewer metal parts than a mechanical system, hydraulic steering has the benefit of being more resistant to corrosion. Hydraulic systems can deal with all torque conditions and may only require fingertip effort.
There are two main parts to hydraulic boat systems – the helm and the cylinder.
Helm – made of a hydraulic pump and valves. When the steering wheel is turned the pump is activated, and a swash plate presses on small piston pumps. The helm is responsible for converting the rotating motion of the steering wheel into a push-pull action on the cable. This cable directs the rudder to move left or right to steer the boat in the skipper’s desired direction. Most helms are rotary and use gears to move the rudder.
Cylinder – moves when fluid is pumped from the helm after the wheel is turned. The cylinder acts between two points on the outboard and doesn’t exert any force on the hull or deck. The cylinder is made up of a ram, bored cylinder and hardware.
Hose – hydraulic hose carries fluid from the helm to the cylinder and back.
