• It is recommended to install the thruster with a support base; the motor is already equipped with support feet.
•
FIG.A
The AC motor must be installed on a separate support from the hull. The support must be dimensioned so as to with-
stand the weight and power specified (table on page 4).
•
FIG.B
The distance (D) between the tunnel centerline (figure B) and the motor support must allow correct alignment between
the drive axle and the gearbox shaft.
•
FIG.C
The angle between the two shafts (gearbox and engine) must not /- 1.5 degrees.
• To position the thruster in the tube, find the halfway
point.
Fig.D
• Use the flange to mark the centre of the holes on
the tube.
Fig.E
• Fix the drilling template on the reference points, making su-
re they are aligned with precision at the half-way point of the
tube.
FIG.F
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.
