Helm Control Systems
4.8 Standard Intercepter Trim Tabs
Interceptor blade style trim tabs are mounted to
each side of the transom. A control panel with a
display provides position monitoring and control of
running trim, heel or heading. Running trim (bow
up/down) adjustments control the hull planing at-
titude, while heel (port and starboard up/down)
adjustments provide control for the hull listing.
A LED display shows the position of the blades
and running trim and heel angles. Control keys
below the display provide manual control of trim
and heel settings. The system also operates in
automatic mode, which is enabled by pressing the
AUTO TRIM function button on the main screen.
The trim blades are programmed to automatically
retract when the engines are shutdown to keep the
actuators clean and set the blades in the retracted
position when leaving the dock. Refer to the trim
tab operating manual for more information on the
operation, programming and maintenance of the
trim system.
When manually setting hull trim, make sure that
the blades are completely retracted when you
leave the dock. If they are not, use the control
keys to retract the blades.
Always establish the intended heading and cruise
speed before adjusting the hull attitude with the
trim blades. After stabilizing speed and direction,
move the blades to achieve a level side to side
running attitude, being careful not to over trim.
After initiating an adjustment, always wait a few
seconds for the change in trim angle to take ef-
fect. Avoid pressing a key while awaiting the trim
reaction. By the time the eect is noticeable the
trim blade will have moved too far and thus the
boat will be in an overcompensated position.
When running at a speed that will result in the boat
falling o plane, extending the blades slightly, bow
down, will improve the running angle and operat-
ing eciency. Too much bow down blade exten-
sion can reduce operating eciency and cause
substantial steering and handling diculties.
Be extremely careful when operating in a following
sea. The eect of trim tabs is amplied under such
conditions. Steering and handling diculties can
result from improper trim tab usage, particularly
in a following sea. Always retract the blades to
the full bow up position in these conditions.
When running at high speeds be sure that the
blades are fully retracted. Only enough trim
blade action should be used to compensate for
any listing. Trim tabs are extremely sensitive at
high speeds. Adjust for this and be prepared to
slow down if diculties arise.
When running into a chop, a slight bow down at-
titude will improve the ride. Be careful not to over
trim. Handling diculties may result.
