CHAPTER 4 STEERING SYSTEM
- 18 - 34z
4.1 STEERING SYSTEM
The 40z has an integrated, electronically controlled hydraulic power steering system which turns
the two Mercruiser stern drives. When running, the 40z is steered as with outboards. Thrust of the
propellers is directed more immediately and precisely from side to side through a 26° arc to steer
the boat.... rather than bouncing the prop wash from a conventional straight shaft propulsion unit
off a rudder.
Control of the sterndrives is transferred from the throttle/shift levers to the AXIUS computer
controlled joystick when the throttle/shift levers are in NEUTRAL and both engines are running.
Emergency Procedure If a fault occurs which prevents one or both of the propulsion units from
being operated with the steering wheel or the transmission does not respond See SOM 63.
4.2 JOYSTICK DOCKING CONTROL
This AXIUS control is used only for docking and
maneuvering at slow speed. Learn to handle the joystick in a
safe and correct manner before you start using the function
in tight quarters.
When the joystick is active, the normal
engine controls are in Neutral and inactive. A computer
operates the drives and shifting. Rotation of the steering
wheel is frozen and it should not be turned, as damage may
occur.
To
Activate : Both engines must be running and the engine
control handles must be IN NEUTRAL. Lower both drives to
the full DOWN position and preferably raise trim tabs as well.
To
Deactivate : Move the engine controls OUT OF
NEUTRAL (forward or reverse).
Maneuvering with Joystick Lean the joystick post in the
direction you’d like to go. Release and the thrust stops. The
boat may keep moving, so you may have to lightly tap it in the opposite direction to stop it. The
top of the joystick is twisted to orient the bow and stern, or to spin the boat completely around on
its own axis. Pretty simple Takes some practice until it becomes completely intuitive. See SOM
26 for a more detailed description of how it works.
