The majority of boats feature mechanical or hydraulic steering systems. The correct steering system for your boat is determined by the size of the boat as well as the kind (and size) of the motor. You may be considering switching from tiller steer outboard to mechanical steering, or from mechanical to hydraulic boat steering.
This page is meant to provide you with an overview of boat steering systems to assist you in selecting the best steering for your boat. It also contains some useful maintenance and repair advice. It is, however, simply general information and should not be used in place of expert advice from a competent marine mechanic. Always seek the advice of or hire a qualified tradesperson in this sector.
What is Hydraulic Steering & How Does it Work?
On boats, hydraulic steering is usually used with mid to high horsepower outboard motors.
Hydraulic steering systems control the steering through a lightweight hydraulic pipe. This provides a smooth, lightweight sensation when turning the steering wheel on larger or more powerful vessels. Hydraulic steering is more corrosion resistant than mechanical steering since it has fewer metal parts. Hydraulic systems can handle any torque conditions with only a fingertip effort.
The helm and the cylinder are the two major components of hydraulic boat systems.
Helm - constructed with a hydraulic pump and valves. The pump is activated when the steering wheel is rotated, and a swash plate presses on little piston pumps. The helm is in charge of transforming the steering wheel's spinning motion into a push-pull action on the cable. This cable instructs the rudder to move left or right to steer the boat in the desired direction of the skipper. Most helms are rotary, with gears used to move the rudder.
When fluid is pumped from the helm after the wheel is spun, the cylinder moves. The cylinder operates between two spots on the outboard and has no effect on the hull or deck. A ram, bored cylinder, and hardware comprise the cylinder.
The hydraulic hose transports fluid from the steering wheel to the cylinder and back.
