INSTALLATION
• The thruster can be installed at any angle within 90° from
vertical.
• If the electric motor is positioned of necessity at an angle
of more than 30° from vertical, a special support must be
constructed.
To position the thruster in the tube, find the half-way point
and move to the value shown (to the right or to the
left. See NOTE page 11) in the table below so that the
propeller is positioned exactly half way along the internal
length of the tunnel.

• Use the flange to mark the centre of the holes on the tube.
• 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 by sandpaper.
• Insert one o-ring into the special seat inside the flange.
