Helm Control Systems
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 con-
tact your Blackn or outboard engine dealer for
assistance.
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 BLACKFIN OR
ENGINE DEALER FOR ASSISTANCE AND DO NOT USE THE
BOAT UNTIL THE SITUATION IS CORRECTED.
Engine Lubrication
Please refer to the engine owner’s manual for
maintenance and lubrication instructions for the
outboard engines.
Trim Tab Maintenance
The trim tab actuators are electric and require no
routine maintenance except to periodically inspect
the tab actuators for corrosion or marine growth
and test the system to ensure that it is operating
properly.
Marine growth can interfere with the proper op-
eration of the trim tab planes and actuators. To
reduce problems due to marine growth, always
return the trim tabs to the full “UP” position af-
ter operating the boat and periodically inspect
and clean marine growth from the actuators and
planes.
If the boat is kept in the water, the trim tab planes
must be equipped with a sacricial anode to pre-
vent galvanic corrosion. Galvanic corrosion is the
corrosion process occurring when dierent metals
are submerged in an electrolyte. Seawater is an
electrolyte and submerged metal components
must be properly protected. The anodes will need
to be changed when they are 75% of their original
size (25% depleted). Refer to the Routine Main-
tenance chapter of this manual for information on
maintaining sacricial anodes.
Trim Tab Actuator, Plane & Anode
To discourage any marine growth on the tabs or
actuators, antifouling paint can be applied. When
applying paint to the actuator, make sure it is fully
retracted. Do not paint the stainless ram above
the area that is exposed when fully retracted. The
bottom paint will damage the O-ring seals when
the ram is retracted and allow seawater to enter
the actuator motor. When painting the trim tabs,
do not apply paint to the sacricial anodes or the
mounting surface under the anode. The sacricial
anode must have full metal to metal contact with
the trim tab plane or it will become ineective.
Contact your dealer or the trim tab manufacturer
for information regarding the correct bottom paint
for the trim tabs.
Refer to the trim tab owner’s manual for additional
maintenance information, specications, trouble-
shooting and operating instructions.
