LS hydraulic steering systems for outboard - Working principle

When the helm is turned to starboard, the pump (1) sucks the oil from the port circuit (2) and pushes it back into the starboard circuit (4), thus driving the cylinder rod (3) which in turn displaces the rudder or motor.

The cylinder body (3) is fixed to the boat.
