Control Systems
tronic and there are no mechanical connections
between the steering wheel and the engine.
For safety and improved tight quarter maneuver-
ing, the controlling software on most systems
senses engine speed and adjusts maximum steer-
ing angle and steering wheel resistance to preset
limits as the engine speed increases or decreases.
The steering angles and steering wheel resistance
at specific engine speeds are programed into the
system at the factory and are not adjustable.
If a fault occurs in the steering system, the con-
trolling software will sense the fault and limit
the engine RPM as a safety precaution and alert
the operator. Each steering control system has
emergency procedures that are specific to the
steering system and type of fault detected. It is
very important to follow the correct procedure to
enable the operator to return safely to port for
repairs. Refer to the engine manufacturer owner’s
manuals for specific information on the operation,
maintenance and emergency procedures for the
steering system installed in your boat.
Steering Wheel
The steering wheel can be tilted to five different
positions by activating the tilt lock lever located
on the bottom side of the helm station. When the
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 specific
information on the steering system.
4.8 Trim Tabs
The recessed trim tabs are mounted to the hull
below the 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 your 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 engine is shutdown to keep the
actuators clean and set the tabs in the full “UP”
position when leaving the dock. Refer to the trim
