ote
Consult the recommendations for the installation and the instruc-
tions on how to build the motor in given in the bow thrusters
manual.
The motor is not fitted to the intermediate flange directly during
the final fitting, but the bottom part of the motor housing must be
fitted first following the instructions given below.

• Position the bottom
half of the housing
on the intermediate
flange.
• Position the packing
supplied on the bot-
tom of the bottom
half of the housing.
• Grease the screw
thread of the bolts
with outboard gear
grease and position
the electric motor
on the intermediate
flange.
• Check that the pro-
peller can be rotated
easily by hand and
that the electric mo-
tor shaft turns as this
is done.
• Check that the shaft
of the tail piece and
the shaft of the elec-
tric motor do not
touch each other.

Electrical installation
n
ote
Make sure that no other electrical parts become loose while con-
necting the power cables.
n
ote
Check all electrical connections after 14 days. Electrical parts (for
example nuts and bolts) can become loose as a result of tempera-
ture variations.
• Connect the cables
already fitted in the
housing correctly
plus (+) and minus (-)
to the motor.
n
ote
Prevent the nut 1 and the bolt
from turning while connect-
ing the cables.
To do this hold nut 1 with an
open-end spanner and do not
turn this spanner while tight-
ening up nut 2.
The torque for bolt 2 is maxi-
mum 11 Nm.
• Connect the
main power ca-
bles.

arning
Sparks from the switch and the fuse can also cause a combus-
tible mixture to ignite!
Therefore, position these in a closed housing (switch box).
• Check that the voltage as given on the motor type plate is the
same as that of the on-board voltage.
Position the battery or batteries as close as possible to the bow
thruster. This allows the main power cables to be short so that there
will be little voltage loss.
