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
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.
• Insert two o-rings into the special seats inside the flange.
