Helm Control Systems
For safety and improved tight quarter maneuver-
ing, the controlling software on most systems
senses engine speed and adjusts maximum steer-
ing angle and steering wheel resistance to preset
limits as the engine speed increases or decreases.
The steering angles and steering wheel resistance
at specific engine speeds are programed into the
system at the factory and are not adjustable.
The steering on each motor is totally indepen-
dent with full redundancy built into the system.
If the steering fails on one engine, the other units
will continue to operate. Should a failure in one
steering system occur, the controlling software
will sense the failure, limit the engine RPM as a
safety precaution and alert the operator.
Each steering control system has emergency pro-
cedures that are specific to the steering system
and type of failure. It is very important to follow
the correct procedure to avoid damage to the en-
gine cowlings if a steering system failure occurs.
Refer to the engine manufacturer owner’s manuals
for specific information on the operation, mainte
-
nance and emergency procedures for the steering
system installed in your boat.
Tilt Steering Wheel
The steering wheel can be tilted to five different
positions by activating the tilt lock lever located
on the bottom of the helm station. When the
lever is released, it automatically locks the steer-
ing wheel at or close to that angle. Refer to the
Typical Yamaha Quad Engine Electronic Controlled Steering
steering manufacturer owner’s manual for specific
information on the steering system.
4.7 Joystick Controls
A joystick control system is an option on triple
engine boats and standard equipment on quads.
The joystick can only be used at slow speeds. It is
engaged by moving the shift and throttle controls to
the neutral position and pressing the ON/OFF but-
ton on the base of the joystick control or the keypad
on the main engine controls. Once activated, the
