3.0 Important notes
F
PROCEEDING WITH THE INSTALLATION IN GOOD LIGHT CONDITIONS.
We recommend using an appropriate personal protective equipment.
QS Seamaster® thrusters are not suitable for installation in potentially explosive environments and/or atmospheres.
Assembly and subsequent checks or repairs must only be carried out by qualied personnel.
3.1 Precautions for the installer

6QSA SERIES USER MANUAL - REV000B
EN
QSA Series
3 - Introduction
3.2 - Installation requirements
It is strongly recommended to entrust a professional with the preparation and positioning of the tunnel in the hull.
These instructions are generic and do not show by any means the details of the operations of preparing the thruster, which
falls under the competence of the shipyard. In case of problems caused by a defective installation, the installer will be held
responsible.
Despite all components and moving mechanical parts are of high quality, the correct installation of the propulsion unit is funda-
mental for a safe and efcient use of the boat, as well as of the propulsion unit itself.
Please note that the installation of such unit is an operation requiring experience and technical competence. It is recommended
to entrust the installation to competent staff and to consult the manufacturer or naval architects to fully evaluate the entity
of the work.
THE PRODUCT MUST BE DISCONNECTED FROM THE HYDRAULIC SYSTEM BEFORE INSTALLING OR PROVIDING
MAINTENANCE.
QS Seamaster® takes no responsibility regarding the inadequate connection of the users to the hydraulic system
and to the safety of itself.
4.0 - Warnings
• QS SEAMASTER®Thrusters have been designed and constructed only for nautical use.
• Do not use these appliances for other uses.
• QS SEAMASTER® shall accept no responsibility for direct or indirect damages caused by improper use of the
appliance or an improper installation.
• The Thruster is not designed to maintain loads generated in particular atmospheric conditions (storms).
• We recommend that you entrust the preparation and the positioning of the tunnel on the hull to a skilled
professional.
• These are generic instructions and do not give details of the preparatory operations for installing the tunnel,
which falls under the competence of the boatyard. The installer shall bear full responsibility for any problems
caused by defective installation of the tunnel.
• Do not install the electric motor near easily inammable objects.

• 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 and at a distance
from the waterline which should be at least 0,75
times the tunnel diameter.
• To avoid cavitation in the propeller, the tunnel
must be positioned as low as possible in the
hull.
• 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.
• For a correct use of the thruster we suggest a maximum length of 3-4 times the tunnel diameter and a minimum length of
1,5 times the tunnel diameter. To limit efciency loss it is acceptable a length that is six times the tunnel diameter.
FFor greater lever effect prefer position B
to position A.

5.1 - Tunnel
• The rounded ends of the tunnel limit the creation of turbulences and cavitations, improving performance of the propeller
thrust and reducing noise levels to a minimum.
• The force produced by the ow 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 ow.
To limit this phenomenon, prepare an indentation in the rear part of the tunnel. Otherwise, create a deector on the front
part of the tunnel.
• If the tunnel is near the waterline, it is advisable to t a grating at the end of the tube.
The grating must have vertical and as large as possible meshes to avoid contrasting the
propeller thrust.
The vertical meshes prevent the entry of most of the oating objects.

• 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 specied (table on page 4).
• FIG.B The distance (D) between the tunnel centerline (gure 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 exceed +/- 1.5 degrees.

• To position the thruster in the tube, nd the halfway
point. Fig.D
• Use the ange 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 ange and tube; this could cause misalignment.
Any resin residues and any other hindrance to correct contact
must be removed by sandpaper.

WARNING: This thruster is not designed for a 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, under pain of
voiding the warranty and thus lifting any responsibility from QS SEAMASTER.
WARNING: Make sure no swimmers or oating objects are in the vicinity before switching on the thruster.
WARNING: There must not be ammable materials in the peak or in the area where the Thruster motor is.
WARNING: Do not operate the bow thruster out of the water for more than 10 seconds.
WARNING: During docking, it is recommended not to leave in the water any free rope, which may be sucked in by the
propellers, thus leading them to break.

9 - Maintenance QSA series
Start-up happens following activation of a DPMS o APMS panel.
QS Seamaster®thrusters are made in materials that are resistant to the sea environment: In any case, it is indispensable
to periodically remove deposits that form on the outer surfaces to avoid corrosions, interruptions and consequent system
inefciency.
WARNING: make sure that the power supply to the electric motor is not switched on when maintenance operations
are carried out.
Dismantle once a year, following the points below:
• Clean propellers, tunnel and gearleg.
• Replace the anodes (carry out this operation more often if needed).
• Replace the propellers if damaged or worn out.
• Check the tightness of all screws.
• Ensure that there is no water seepage inside.
• Check that all electrical connections are well tightened and oxide-less.
• Check that the batteries are in good conditions.
• Remove the graphite residues resulting from the normal motor brushes use.
WARNING: do not paint the anodes, the sealings and the gearleg’s shafts where the propellers are lodged.
ACCORDING TO THE USE WE RECOMMEND CHECKING PERIODICALLY THE OIL SEALS AND IF NECESSARY REPLACING THEM.
