Cosmetic Care & Maintenance
Trim refers to the running angle of the boat while underway
to achieve the most ef
fi cient planning angle. Check all
electrical connections for tightness, corrosion, and cha fi ng.
All mechanical trim tab components should be checked
periodically. If a malfunctioning tab is suspected, run
each tab in and out while someone looks at each tab to
make sure it is moving up and down the proper distance.
Replace zinc anodes when at one half their life as
determined by size. Check anodes twice a month in
salt environments.
The trim tabs may be painted for corrosion protection.
Do not paint the anodes as they protect the tabs from
galvanic corrosion.
As these trim tabs are electrically operated there is no
requirement for hydraulic oil.
TRIM TABS TRANSFORMER-ISOLATION
The isolation transformer option contains no moving
parts and requires very little maintenance because of its
durable construction. Periodic inspection and care are
recommended practices especially if the transformer is
operating in a harsh environment.
A periodic inspection for loose connections, condition
of terminal board, overheating, rust, paint, deterioration,
and general condition of the unit by a quali
fi ed service
technician is recommended.
The following information is included for the quali fi ed
service personnel only.
If there is a malfunction of the transformer, fi rst check to
see if all connections are tight and then retest.
Removal of dust, dirt and debris from the external
enclosure surfaces is encouraged and may be performed
while the unit is in operation (Do not use water).
Internal maintenance would include the inspection and
tightening of bolted connections. Removal of dirt can be
accomplished using a vacuum cleaner or low pressure (less
than 20 psi) dry compressed air.
If a transformer is being inspected, cleaned or worked
on, these safety steps must be observed.
1. Remove all power from the sources in the primary and
secondary circuits.
2. Remove all fuses from the power source. Additionally,
trip circuit breakers and take appropriate action to prevent
the accidental resetting of the circuit breakers.
3. Short out transformer secondaries before connecting
and disconnecting equipment.
4. Always connect a load to the secondary side of the
transformer before applying power to the primary.
