and a hydraulic steering 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 causing the 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.
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 steering wheel at or close to that angle. Refer to the
steering manufacturer owner’s manual for specific informa-
tion on the steering system.
Dual outboards are coupled at the tiller arms by a tie bar
and controlled by the steering cylinder. The engines must
be aligned to provide maximum stability on straight ahead
runs and proper tracking through corners. Dual outboards
are aligned so the engines are towed out 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 platform and inte-
grated 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.
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 to take effect. Avoid depressing
the switch while awaiting the trim plane reaction. By the time
the effect is noticeable the trim tab plane will have moved too
far and thus the boat will be in an overcompensated position.
When running at a speed that will result in the boat falling off
plane, lowering the tabs slightly, bow down, will improve the
running angle and operating efficiency. Too much bow down
tabs can reduce operating efficiency and cause substantial
steering and handling difficulties.

Be extremely careful when operating in a following sea. The
effect of trim tabs is amplified under such conditions. Steer-
ing and handling difficulties can result from improper trim
tab usage, particularly in a following sea. Always raise the
tabs to the full bow up position in these conditions.
When running at high speeds be sure that the tabs are in the
full “UP” position. Only enough trim plane action should be
used to compensate for any listing. Trim tabs are extremely
sensitive at high speeds. Adjust for this and be prepared to
slow down if difficulties arise.
