Boat steering controls are not self-
centering. Always keep a secure grip on
the steering wheel to maintain full boat
control.
Mechanical steering helm controls
transfer the rotary motion of the steering
wheel to linear cable motion, which
pushes or pulls the engine’s steering
arm. Some boats are equipped with two
mechanical cables to provide positive
steering control and additional safety in
case one cable fails.
Power-assisted mechanical systems use
hydraulic force to assist the manual
rotary motion of the helm’s movement,
providing easier steering for the operator.
Hydraulic systems use hydraulic
pressure from a pump connected to the
helm to move hydraulic fluid through
hoses, and then to move hydraulic
cylinders connected to the engine’s
steering arm. A reservoir, either separate
or integral to the pump, holds extra fluid
and maintains a pressure head to prevent air from entering the system.
SHIFT AND THROTTLE CONTROLS
Knowing how to operate the shift and throttle controls of the boat is essential for
safe and proper operation.
The following basic and typical information may not apply to your specific shift
control. See the Engine Operator’s Manual or control manufacturer’s instructions for
