Hydraulic Steering
The basic hydraulic steering system for a single engine boat contains a steering wheel, a hydraulic
helm pump, a hydraulic steering cylinder, and hydraulic hoses.
Operation
When turning the steering wheel, the helm pump forces hydraulic fluid through hoses to and from the
steering cylinder which is connected to the tiller arm on the engine. The cylinder moves the tiller arm
to either port or starboard, depending upon the direction the steering wheel is turned.
