4.9 Zipwake Trim Tabs (Optional)
Interceptor blade style trim tabs are mounted to
each side of the transom. A control panel with
a 3D display provides position monitoring and
control of running trim, heel or heading. Running
trim (bow up/down) adjustments control the hull
planing attitude, 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 wheels
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 button.
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 Zip-
wake 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 lly retracted when you leave the
dock. If they are not, use the control wheel 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 rotating a wheel 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.
