and clean marine growth from the actuators and
planes.
There are two trim tab pumps located in the stern
mechanical systems compartment. The fluid level
should be checked often. Keep the fluid level be
-
tween the marks on the trim tab pump reservoirs.
The trim tabs are attached to the bonding sys-
tem and each tab is equipped with an anode to
prevent galvanic corrosion when the boat is salt
water. Galvanic corrosion is the corrosion 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 monitored
and 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. Con-
tact 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.
Periodically inspect the components inside the
hull for leaks and for loose or corroded electrical
connections. Signs of leaks and loose or corroded
electrical connections should be corrected imme-
diately 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 propellers. If the propellers are damaged or
heavily contaminated, they should be replaced.
The thruster is protected from galvanic corrosion
by an anode on each propeller shaft. The anodes
should be inspected regularly and changed when
they are 75% of their original size.
If the boat is kept in the water, the anodes 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 Scout dealer or the bow
thruster manufacturer for information regarding
the correct bottom paint and application.
Refer to the bow thruster owner’s manual for ad-
ditional maintenance information, specifications,
troubleshooting and operating instructions.
