Engine Lubrication
Refer to the engine owner’s manual for mainte-

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 opera-
tion of the trim tab planes and actuators. To reduce
problems due to marine growth, always return the
trim tabs to the full “UP” position after 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 tabs must
be equipped with a sacrificial anode to prevent
galvanic corrosion. Galvanic corrosion is the cor-
rosion process occurring when different 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 Maintenance
chapter of this manual for information on maintain-
ing sacrificial anodes.
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 sacrificial anodes or the
mounting surface under the anode. The sacrificial

anode must have full metal to metal contact with
the trim tab plane or it will become ineffective.
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, specifications, trouble

shooting and operating instructions.
