An oil reservoir, engine hydraulic pump, and a res-
ervoir at the helm allows easy system fill. It is
important that the fluid level in the reservoirs is
checked frequently and maintained at or near the
maximum level. Both reservoirs use the same hy-
draulic fluid.
Refer to the engine and steering system manu-
facturer owner’s manuals for specific information
on the operation and maintenance for the steer-
ing system.
Helm and Outdrives
The steering wheel can be tilted to five different
positions by activating the tilt lock lever located
on the bottom side of the helm. When the lever is
released, it automatically locks the steering wheel
at or close to that angle.
Dual engine sterndrive boats have two outdrives.
These are coupled together at the tiller arms or
the drives themselves by a tie bar. Mercruiser
drives are set parallel and Volvo drives are toed
in 1/2” at the aft end of the cavitation plates to
provide maximum stability on straight ahead runs
and proper tracking through corners. Outdrive or
steering system damage may require the outdrives
to be realigned.
Please refer to the engine or steering system
owner’s manual or contact your dealer for infor-
mation on the power steering system.
2.6 Trim Tabs
The trim tabs are mounted
to the hull on the transom
below the swim platform.
Dual rocker switches in the
helm are used to control
the trim tabs. The switches
are labeled and control bow
up and down movements.
They also control 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 atti-
tude 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 op-
erating efficiency. Positioning trim tab too far in
the down position can reduce operating efficiency
and cause substantial steering and handling diffi-
culties.
Be extremely careful when operating in a following
sea. The effect of trim tabs is amplified under
such conditions. Steering and handling difficul-
ties can result from improper trim tab usage, par-
ticularly 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.
