CAUTION
lever is released, it automatically locks the steer-
ing wheel at or close to that angle. Refer to the
steering manufacturer owner’s manual for specic
information on the steering system.
Steering Cylinder
Single outboard engines are equipped with one
hydraulic steering cylinder mounted on the engine
that is connected directly to the engine tiller arm.
4.8 Trim Tabs
The trim tabs are mounted on the transom be-
low the 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 move-
ments. Bow up and bow down will control the hull
planing attitude, while port and starboard up and
down provides control for the hull listing. Before
leaving the dock or loading the boat on a trailer
or forklift, make sure that the tabs are in the full
“UP” position by holding the control in the bow up
position for ten (10) seconds.
LED Indicator Switch (Optional)
If your boat is equipped with the optional LED trim
indicator switch, red LED lights next to each switch
display the position of your trim tabs. Additionally,
the switch is wired so the trim tabs automatically
retract to the “full-up” position when the ignition
switch is turned off.
The LED display indicates trim tab deection.
When one LED indicator light is lit at the top of
each display, the tabs are in the “full-up” (bow up)
position. As the tabs are lowered (bow down) ad-
ditional indicator LED lights become lit to indicate
the degree of tab plane travel. When all LED lights
are lit, the tabs are fully extended (bow down).
THE TRIM TABS CAN BE DAMAGED BY BOAT TRAILERS IF THE
BUNKS EXTEND BEYOND THE TRANSOM OR THE BOAT IS
NOT CENTERED PROPERLY. THEY CAN ALSO BE DAMAGED
BY FORK LIFTS AT DRY STACK MARINAS DURING LIFTING.
TO REDUCE THE POSSIBILITY OF DAMAGE, ALWAYS MAKE
SURE THE TABS ARE IN THE FULL UP POSITION BEFORE
LOADING YOUR BOAT ON A TRAILER OR HAVING IT LIFTED
BY A FORK LIFT.

Trim Tab Operation
Before leaving the dock, make sure that the tabs
are in the full “UP” position by holding the control
in the bow up position for ten (10) seconds.
Always establish the intended heading and cruise
speed before attempting to adjust the hull attitude
with the trim tabs. After stabilizing speed and
direction, move the trim tabs to achieve a level
side to side running attitude being careful not to
over trim.
