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.

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.

INSTALLATION

BOW THRUSTER BTQ250 - BTQ300 IT EN - REV006C

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.

PROPELLER

CONTROL PANEL

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

onto the gearleg

; assemble the propellers

and

at the gearleg, fitting them onto the drive pins

and anchor the propellers with the self-braking nuts

The anodes

fit onto the nut

and are then anchored with the screws

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

propeller

on the right-hand side of the gearleg (see figure).
