Everglades CC 243 2012 - 4.9 Control Systems Maintenance

Helm Control Systems
WARNING
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 efciency. Too much bow down tabs can
reduce operating efciency and cause substantial
steering and handling difculties.
Be extremely careful when operating in a following
sea. The effect of trim tabs is amplied under such
conditions. Steering and handling difculties 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 difculties arise.
When running into a chop, a slight bow down at-
titude will improve the ride. Be careful not to over
trim. Handling difculties may result.
4.9 Control Systems Maintenance
Control Maintenance
Periodic inspection of the control systems and all
connections should be made. Signs of rust, cor-
rosion, wear or other deterioration should imme-
diately be serviced. Generally, periodic lubrication
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 adjustments become necessary, see your
Everglades dealer.
DO NOT ATTEMPT CONTROL ADJUSTMENTS UNLESS YOU ARE
FAMILIAR WITH SERVICING CONTROL SYSTEM PROCEDURES.
CONTROL MISADJUSTMENT CAN CAUSE LOSS OF CONTROL
AND SEVERE ENGINE OR LOWER UNIT DAMAGE.
Steering System Maintenance
A periodic inspection of all steering hoses, link-
age and helm assemblies should be made. Signs
of corrosion, cracking, loosening of fastenings,
excessive wear or deterioration should be cor-
rected immediately. Failure to do so could lead to
steering system failure that would result in loss of
control. Generally, periodic lubrication of all mov-
ing parts and connections with a light waterproof
grease is in order.
The uid level for the hydraulic steering should be
checked frequently and maintained at the proper
level. The steering uid level at the vent/ll plug,
located on the helm above the steering wheel,
should be maintained at no less than 1/2” below
the bottom of the ller cap threads.
