Helm Control Systems
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.
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
Crevalle dealer.
WARNING
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.
Hydraulic Steering System Maintenance
A periodic inspection of all steering hoses, linkage
and helm assemblies should be made. Signs of
corrosion, cracking, loosening of fasteners, ex-
cessive wear or deterioration should be corrected
immediately.
The fluid level for the hydraulic steering should
be checked frequently and maintained at the
proper level. The steering fluid level should be
maintained at no less than 1/2” below the bottom
of the fill plug hole on the hydraulic power assist
pump reservoir located in the mechanical systems
compartment. Only use power steering fluid rec -
ommended by the steering system manufacturer
when adding fluid.
If your boat is equipped with an after market
tower, the procedure for checking the steering
fluid level and adding fluid may be different. Refer
to the steering system manual for instructions on
checking and filling the steering system on your
boat.
Generally, periodic lubrication of all moving parts
and connections with a light waterproof grease is
in order. Check the hydraulic hoses and fittings for
chaffing, rub marks and leaks. Replace if neces -
sary. Failure to do so could lead to steering system
failure that would result in loss of control. When
new or after repairs, hydraulic steering systems
may need to have all air purged from the system.
Only use hydraulic steering fluid recommended
by the steering system manufacturer. Difficult
steering and premature seal failure can result if
the wrong fluid is used in the steering system.
Review the information provided by the steering
system manufacturer for proper specifications
and details on system service and maintenance.
Electronic Steering and Control Systems
Maintenance
Electronic steering and control systems are sup-
plied by the engine manufacturer. The systems
have maintenance requirements that are specific
to the engines and control options installed in
your boat.
You should refer to the engine and controls sys-
tems owner’s manuals for information and mainte-
nance on the control and steering system installed
in your boat. Their recommendations should be
followed exactly.
The engine controls and steering systems are fully
electronic and activated by micro processors and
controlling software in each engine controller. If
adjustment becomes necessary do not attempt to
address the problem yourself. You should contact
your Crevalle or outboard engine dealer for as-
sistance.
WARNING
IMPROPERLY ADJUSTED ELECTRONIC ENGINE CONTROLS
CAN CAUSE LOSS OF CONTROL AND SEVERE ENGINE
DAMAGE. IF YOUR CONTROLS ARE NOT OPERATING
PROPERLY, DO NOT ATTEMPT CONTROL SYSTEM
ADJUSTMENTS YOURSELF. CONTACT YOUR CREVALLE OR
ENGINE DEALER FOR ASSISTANCE AND DO NOT USE THE
BOAT UNTIL THE SITUATION IS CORRECTED.
