INSTALLATION REQUISITES:
THE TUNNEL
• The position of the tunnel will depend on the interior and exterior shape of the boats bow.
• Optimal positioning of the tunnel will be in the bow and as low as possible, at least 0.75 times the tunnel diameter from the
waterline.
• To avoid cavitation in the propeller, the tunnel
must be positioned as low as possible.
• The lever effect in the boat is proportional to the
increase of the distance (L1 and L2) between the
barycentre and the position of the tunnel A and B.
• An increase in the length of the tunnel increases
the effect of the loss of charge, decreasing the
nominal driving force.
• To limit losing charge, the optimal length is equal
to 3-4 times the tube diameter; a ratio of up to 6
can be tolerated.
F
For greater lever effect prefer position B to
position A.

• The rounded ends of the tunnel prevent the creation of turbulence and cavitation, improving performance of the propeller
thrust and reducing noise levels to a minimum.
• The force produced by the flow of the water when the boat is moving produces resistance on the rear face of the tunnel,
which is an area exposed frontally to the water flow.
To limit this phenomenon, prepare an indentation in the rear part of the tunnel. Otherwise, create a deflector on the front
part of the tunnel.
• If the tunnel is near the waterline, it is advisable to fit a grating at the end
of the tube.
The grating must have as large a vertical mesh as possible to avoid contrast-
ing the propeller thrust. The vertical mesh prevents the entry of most of the
floating objects.

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

GEARLEG AND MOTOR SUPPORT FLANGE
SILICONE
• Grease the terminal part of the gearleg shaft; fit the small
key into its seat.
• Insert the elastic joint in the terminal part of the gearleg
shaft.
• Insert the motor onto the elastic joint; fasten it with the 4
screws and washers provided.
• Grease the terminal part of the gearleg shaft; fit the small
key into its seat.
• Proceed with fitting the gearleg with the
special seal gasket.
• For further protection against the entry
of water, apply silicone for nautical use
around the point of contact between flange
and tube.
• Fasten everything to the flange using the
special screws and washers.

To install the control panel, consult the “TCD 1022 - TCD 10422 - TCD 1044” instruction manuals.
LOCTITE
WARNING: on conclusion of assembly,
make sure that the propeller is exactly posi-
tioned at the central point of the tunnel.
PROPELLER FITTING
Insert the drive keys A onto the gearleg B ; assemble the propellers C and D at the gearleg, fitting them onto the drive pins A
and anchor the propellers with the self-braking nuts
E .
The anodes F fit onto the nut E and are then anchored with the screws G which must be wetted with thread-locking adhesive
(such as loctite).

WARNING - USAGE
WARNING
WARNING: this bow thruster is not designed for continuous use.
It is equipped with protections which limit its operation at a maximum time span, as reported on the controls’ manual.
It is strongly forbidden to bypass or modify such protections in order to increase the operating time span, lest voiding
the warranty and thus lifting any responsibility from Quick SPA.
WARNING: make sure no swimmers or floating objects are in the vicinity before switching on the thruster.
WARNING: there must not be flammable materials in the peak or in the area where the Bow Thruster motor is.
WARNING: do not operate the bow thruster out of the water for more than 10 seconds.
WARNING: during mooring, it is recommended not to leave in the water any free line, which may be sucked in by the
propellers, thus leading them to break.
USE OF BOW THRUSTER
START-UP
Start-up happens following activation of a TCD panel.
To use the thruster refer to the manual of the TCD control.
In case the bow thruster needs to be installed on the opposite
position, the connection of the two wires (blue and grey) to the
control cable on the reversing contactor unit must be inverted.
NOTE: the bow thruster must be installed with the RH propeller
on the right-hand side of the gearleg (see figure).
