• If the engines are trimmed up, the operator should manually adjust the trim to full down, provided doing so does not
create a hazard. The system will not automatically trim the engines down when the joystick is engaged.
•
For more details, refer to Auto Trim.
IMPORTANT: After joystick operation and before attempting to put the vessel on plane, the trim position must be set to an
angle that allows for normal operation. The computer controlled system will not return the drives to the position they were
at before the joystick was engaged.
3. Move all of the electronic remote control levers to neutral. For Zero Effort controls, shift into neutral and place the throttle
levers at idle.
4. Move the joystick in the direction that you want the boat to move, or twist the joystick in the direction that you want the boat
to rotate. The joystick can be moved and rotated at the same time.
The following picture gives a limited example of the basic responses to inputs from the joystick, and should be used for
reference only. The pictures show an approximate correlation between joystick inputs and the corresponding movement of the
vessel. Exact maneuvers will require multiple joystick inputs and additional user corrections to maintain the maneuver.
NOTE: The joystick does not have detents. It can be positioned at any of the indicated arrows or anywhere in‑between.
a - Forward
b - Crab to forward by starboard
c - Lateral to starboard
d - Crab to reverse by starboard
e - Reverse
f - Crab to reverse by port
g - Lateral to port
h - Crab to forward by port
i - Port yaw
j - Starboard yaw
Centering the Drives after Joystick Operation
Upon releasing the joystick, the drives will remain in their last commanded position, unless the last command was yaw (twisting
the joystick). To center the drives, move the steering wheel or twist the joystick.
Moving the ERC Handles while in Joystick Mode
If the ERC handles are moved while the joystick is in operation, a noncritical fault will be set in the system. A six‑second
intermittent beep will sound, an ERC override fault will be displayed on the VesselView, and the ERC will take command of the
vessel from the joystick. Once the ERC handles are returned to neutral, the joystick can again assume control of the vessel.
Auto Trim
The Joystick Piloting system includes an auto trim feature that works with Skyhook station keeping and joystick operations. This
feature will automatically trim the drives up or down to a position preset by the boat manufacturer.
Enabling Auto Trim
Auto trim is enabled whenever the ERC levers are moved into a gear and then back into neutral, or when the engines are
started.
Auto Trim Up
When the operator assumes control of the vessel with the joystick, auto trim will raise any drive that is trimmed below the
preset position to that preset position, provided that auto trim has been enabled as described above. Auto trim will similarly
raise the drives when Skyhook is engaged. Once the drives have been trimmed up to the preset point, auto trim is disabled
and can only be reenabled as described previously.
