any point, any problem that will alter the
boat's course, rising from malfunction of
interceptors, should be dealt immediately
by the operator. At no circumstances, fault
of our interceptor equipment leading to any
kind of accident, creates liability for the
manufacturer.

1. For high speed boats, overtrim may cause unexpectable turn. Improper use of trim tabs, may result to
accident or injury.
2. DO NOT PLACE YOUR FINGERS ON THE SIDES OF THE INTERCEPTORS (Figure 4). Severe injury danger!!!

Required Tools for Installation
Sikaflex gun Marking tool
(pencil or marker)
Make sure there are no obstructions behind the
drilling area (tanks, fuel lines, cabling) which can
be damaged or prevent the installation (Figure 1).
Before Installation
Attention! Please make sure that the pipe
insertion hole is accessible from the engine room
(Figure 2).
A good hint is that the closer the units are to the water line, the best the bank control of the boat will be
(Figure 3).
Hole Saw Ø67
If there is a double installation on the boat please
allow a 18 to 20 mm space between them (Figure

Transom
Interceptor
Proper interceptor installation in transom
For maximum performance and less drag, install interceptors on the transom so blades deploy vertically.
If transom is not vertical to water plane, correct the angle by using wedges or other means.
If the boat's transom has a significant curvature, it is necessary to create a flat plane for the installation
(acceptable flatness tolerance: 2mm).
Optimal Less performance Correct angle
More drag

For aluminum hulls, it is suggested Isolation Plates between hull and interceptors to be installed. You can
find installation instructions in the Isolation Plates Kit.

The 3DHC Controller
The 3DHC controller operation
Interceptors operate when voltage comes from the ignition.
When there is no voltage from the ignition, system does not
work.
System Reset - Retracting
The system resets and interceptors retract automatically:
ŸOn Engine start
ŸOn Engine stop
ŸOn simultaneously pressing the UP + DOWN buttons for
1 second.
Note: During reset process controller LEDs are flashing.
Night and day mode
T h e i n d i c a t i on b r i g h t n e s s c h an ge s by p r e s s i n g
simultaneously the buttons LEFT + RIGHT for 1 second.
Memory
Setting the desired trim angle
You may save the desired trim angle for the cruising speed.
Just manually adjust the position and then press
simultaneously any diagonal press buttons for about 3
seconds. This position of trim tabs is stored in 3DHC
memory and the power-on led is flashing to confirm the
setting.
Whenever the user presses instantaneously two diagonal
press buttons, the trim tabs get the preset position.
The saved position is stored even after switching off the
main switch of the boat.
Maintenance
Check connectors for corrosion or liquid pollution.
Check in regular intervals the condition of the sacrifice
anodes. Below 50% in volume, anodes must be replaced.
When the boat is out of the water (end of season):
a. extend the blades
b. spread the decalcifying liquid with a brush
c. let it for 15-20 min
d. wash out with clean water
e. retract the blades
Every two years remove the cover and clean the inside of
the units, using water pressure.
Every three years check the springs condition.
