1 PRODUCT DESCRIPTION
1.1 Trim tab description
The use of the tabs allows the boat to maintain an
adequate trim according to the different navigation
conditions, optimizing the performance. If necessary
(Pict.1), the tab drive rectifies and rebalances the boat
trim (Pict. 2), ensuring a higher engine efficiency and
speed, a considerable fuel saving and navigation safety.
The tabs fixed to the lower edge of the transom act as a
movable extension of the boat hull, increasing the
stability in several conditions.
Their working principle is the following: the water, flowing
on the tab surface, causes the stern lifting as the tab is
lowered. According to this principle, it is possible to
change the tab lowering up to reaching a trim that can
ensure an optimal performance for each situation.
The trim tabs described in this manual consist of:
1
Actuator
2
Connection bracket to the transom
Electric cable (2 m - 6.6 ft)

Joystick - Control system
1.2 Operation
The joystick allows an easy use of the Trim Tab system.
Thanks to this control system, the user can focus on the
boat trim, regardless of the tab position.
The electromechanical actuators (2) that allow changing
the inclination angle of tab (3) are controlled by means of
the joystick (1) that is located on the dashboard or on the
upper station.
Joystick function description:
- By jogging the lever forward, the boat bow goes down;
- By jogging the lever backward, the boat bow goes up;
- By jogging the lever rightward, the boat tilts to starboard
- By jogging the lever leftward, the boat tilts to port
When running at idle or when the engine turns off, the electronic system enables the AUTO LINE-UP function
automatically. It allows putting the tabs in rest position.
