We recommend installing the thruster with a support. The motor is supplied with support feet, which are already fitted.

•
FIG. 1
The AC motor must be installed on a support adequately sized to support the specified weight and power (see table on
• page 4).
•
FIG. 2
The distance (D) between the centreline of the tunnel and the motor support must allow for correct alignment of motor
• axle to gearbox axle.
•
FIG. 3
The angle between the two shafts (gearbox and motor) shall not /- 1.5°.
•
FIG. 4
To position the thruster in the tube, find the half-way point.

• FIG. 6
Fix the drilling template on the reference points, making sure they are
aligned with precision at the half-way point of the tube.
N.B. All holes must be exactly aligned with the half-way point of the
tunnel, since tolerance between propeller and tunnel is minimal.
Take care that there are no resin residues in the contact area between flange and
tube; this could cause misalignment. Any resin residues and any other hindrance
to correct contact must be removed with sandpaper.
• Fig. 7A / Fig. 7B
Insert two O-rings into the special
seats inside the flange.
