• The thruster can be installed at any angle within 90° from
vertical.
• If the electric motor is positioned of necessity at an an-
gle of more than 30° from vertical, a special support must
be constructed.

• To position the thruster in the tube, find the half-way
point so that the flange 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.
