OS 255
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 waiting for the trim plane reac-
tion. By the time the effect is noticeable the
trim tab plane may have moved too far and
thus the boat may be in an overcompen-
sated position.
When running at speeds resulting in the boat
falling off plane, lowering the tabs slightly,
bow down, will improve the running angle
and operating efficiency. However, too much
bow down trim can reduce operating effi-
ciency and cause substantial steering and
handling difficulties.
When running at high speeds be sure the
tabs are in the full “UP” position. Use only
enough trim plane action to compensate for
any listing. Trim tabs are extremely sensitive
at high speeds. Adjust for this and be pre-
pared to slow down if difficulties arise.
Be extremely careful when operating in a fol-
lowing sea. Such conditions cause an ampli-
fied trim tab effect. 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 into a chop, a slight bow
down attitude will improve the ride. Be care-
ful not to over trim. Handling difficulties may
result.
2.8 Compass
The compass is on top of the helm. Read the
instructions on “Compass Compensation”
provided in the literature packet to adjust the
compass. A factory-adjusted compass is
inaccurate due to the influence of electrical
instrumentation and equipment unique to
your boat. Therefore, have the compass pro-
fessionally adjusted after the electronics and
additional electrical accessories installation
and before operating the boat.
2.9 Control Systems
Maintenance
Control Maintenance
Periodically inspect the control systems and
all connections. Service any signs of rust,
corrosion, wear, or other deterioration. Peri-
odically lubricate all moving parts and con-
nections using lightweight, waterproof
grease.
Control system adjustments may become
necessary periodically. If adjustments
become necessary, see your Pursuit dealer.
Steering System Maintenance
Periodically inspect of all steering hoses,
linkage and helm assemblies. Signs of cor-
rosion, cracking, loosening of fastenings,
excessive wear, or deterioration require
immediate correction.
Frequently check and maintain proper fluid
levels for hydraulic steering. Periodically
lubricate all moving parts and connections
using lightweight, waterproof grease. Failure
to do so can lead to steering system failure,
resulting in loss of control.
When new, or after repairs, hydraulic steer-
ing systems may need to have air purged
from the system. Review the information
provided by the steering manufacturer for
proper specifications and details on system
service and maintenance.
!
WARNING
Inspect and maintain control and
steering systems regularly. Do not
attempt adjustments unless you are
familiar with steering control system
service procedures. Control misad-
justment can cause loss of control
and severe engine or lower unit dam-
age.
