2.6 Steering System
The steering system is hydraulic and made of two
main components: the helm assembly and the
hydraulic cylinder. The helm unit acts as both a
fluid reservoir and pump. Turning of the helm, or
steering wheel, pumps the fluid in the hydraulic
hoses and activates the hydraulic cylinder caus-
ing the motor or motors to turn. A slight clicking
sound may be heard as the wheel is turned. This
sound is the opening and closing of valves in the
helm unit and is normal. Refer to the steering
manufacturer owner’s manual for specific informa-
tion on the steering system.
Steering Cylinders and Tie Bar
Single outboard engines are equipped with one
hydraulic steering cylinder mounted on the engine
that is connected directly to the engine tiller arm.
Dual outboards are coupled near the tiller arms by
a tie bar and controlled by one steering cylinder
mounted on the starboard engine.
Dual engines must be aligned to provide maxi-
mum stability on straight ahead runs and proper
tracking through corners. They are aligned so the
engines are towed in slightly (.25” to .5”) at the
propellers. Engine or steering system damage
may require the engines to be realigned.
2.7 Trim Tabs
The trim tabs are recessed below the swim plat-
form 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 trim indicator switch
is optional.
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.
After depressing a trim tab switch, always wait
a few seconds for the change in the trim plane
