NOTICE:
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 ma-
rinas 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.
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 overcompen-
sated 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 operat-
ing efficiency. Positioning trim tabs too far in the
down position 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. Steering 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.
When running into a chop, a slight bow down at-
titude will improve the ride. Be careful not to over
trim. Handling difficulties may result.
An indicator next to each switch displays the posi-
tion of your trim tabs. The display indicates trim
tab deflection. When the indicator is at the bottom
of the display, the tabs are in the "full-up" (bow
up) position. When the indicator is at or near the
top of the display, the tabs are fully extended (bow

down). The trim tabs are wired so they automati-
cally retract when the ignition switch is turned off.

4.7 Control Systems Maintenance

Control Maintenance
Periodic inspection of the control systems and
all connections should be made. Signs of rust,
corrosion, wear, or other deterioration should be
serviced immediately. Generally, periodic lubrica-
tion of all moving parts and connections with a
light waterproof grease is in order.
Lubrication should be performed as often as nec-
essary to keep the system operating smoothly.
Control system adjustments may become neces-
sary. If adjustment becomes necessary, see your
Monterey dealer.
