Helm Control Systems
4.7 Joystick Controls
A joystick control system is an option on some
engine installations with electronic steering. 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
button on the base of the joystick control or the
keypad on the main engine controls. Once acti-
vated, the boat moves in the direction the joystick
is pushed with the engine speed increasing the
further the stick is pushed, up to preset limits.
Turning the knob on the top of the joystick rotates
the boat in the direction the knob is turned. An-
other button on the joystick or engine control key
pad raises the preset engine speed for maneuver-
ing in high winds and/or strong tides.
When the joystick is released, it automatically
returns to center, the engines shift to neutral,
rotate to the straight ahead position, and the
engine speed is reduced to idle. It is deactivated
by pressing the ON/OFF button at the base of the
joystick or control keypad or by moving the shift
and throttle control levers.
Both engines must be running for the joystick
control to maneuver boat properly.
Always refer to the engine manufacturer owner’s
manuals for specic information on the operation
and maintenance for the joystick and steering
control systems on your boat.
4.8 Trim Tabs
The trim tabs are mounted to the hull below
the swim platform and integrated transom engine
mounting system. A dual rocker switch is used to
control the trim tabs. The switch controls bow up
and down movements. It also controls starboard
and port up and down movements. Bow up and
bow down will control the hull planing attitude, while
port and starboard up and down provides control
for the hull listing.
An LED indicator built into the switch displays the
position of the trim tabs. When one LED is ashing
at the top of the display, the tabs are in the “full-up”
(bow up) position. When all LED lights are lit from
the top to the bottom of the display, the tabs are
fully extended (bow down).
The trim tabs are programmed to automatically
retract when the engines are shutdown to keep
the actuators clean and set the tabs in the full “UP”

position when leaving the dock. Refer to the trim
tab operating manual for more information on the
operation and programming of the trim tabs.
Before leaving the dock, make sure that the tabs
are in the full “UP” position. If they are not, press
and hold the control in the bow up position for ten
(10) seconds to fully retract the tabs.
