specifications and details on system service and
maintenance.
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 tabs
must be equipped with a zinc 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. Refer to the Routine Maintenance chapter of
this manual for information on maintaining zinc
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 retracted. The
bottom paint will damage the O-ring seals when
the ram is retracted and allow seawater to enter
the actuator motor. 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.
Bow Thruster Maintenance (Optional)
The bow thruster is mounted in the forward bilge
below the V-Berth. Periodically inspect the com-
ponents inside the hull for leaks and for loose or
corroded electrical connections. Signs of leaks
and loose or corroded electrical connections should
be corrected immediately by a qualified marine
technician.
Marine growth, weeds and debris can interfere
with the proper operation of the bow thruster so
you should inspect the tunnel regularly and clean
as necessary. This is particularly important when
operating in areas with weeds or if the thruster is
not responding normally. You should also check
the propeller. If the propeller is damaged or heav-
ily contaminated, it should be replaced.
The thruster is protected from galvanic corrosion
by an anode on the propeller shaft. The anode
should be inspected regularly and changed when
it is 75% of it’s original size.
If the boat is kept in the water, the anode should
be inspected at least once every 3-4 months.
Antifouling paint can be applied to the tunnel and
underwater components to discourage marine
growth. Bow thrusters have specific requirements
for the type of antifouling paint that can be used
and where it can be applied. Applying the wrong
paint or paint that is not applied correctly can
damage the bow thruster and void the warranty.
Contact your authorized Everglades dealer or the
bow thruster manufacturer for information regard-
ing the correct bottom paint and application.
Refer to the bow thruster owner’s manual for ad-
ditional maintenance information, specifications,
troubleshooting and operating instructions.
