Helm Control Systems
4.6 Steering System
Electronic Steering
Your boat is equipped with an electronic steering
system that provides precise and responsive steer-
ing. Electronic steering is available with or without
a joystick control.
Notice:
Some engines with Helm Master electronic
steering do not have external electronically
controlled steering pumps. All steering com-
ponents that move each engine are mounted
inside the engine cowling.
The system is 100% electronic and there are
no mechanical connections between the steer-
ing wheel and the drives. Each engine is turned
independently allowing improved tight quarter
maneuvering and the convenience of an optional
Joystick control at the helm.
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 unit
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.
