Helm Control Systems
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. Another button
on the joystick or engine control key pad raises
the preset engine speed for maneuvering in high
winds and/or strong tides.
When the joystick is released, it automatically re-
turns to center, the engines shift to neutral, rotate
to the straight ahead position, and 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.
All engines on triple and quad engine boats must
be running for the joystick control to maneuver
boat properly.
Always refer to the engine manufacturer own-
er’s manuals for specific information on the
operation and maintenance for the joystick
and steering control systems on your boat.
4.8 Trim Tabs
The recessed 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.
A LED indicator built into the switch displays the
position of the trim tabs. When one LED is flash
-
ing 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.
