Vetus STERN THRUSTER Instrucciones De Instalación página 5

In case that the available
height at the stern is insuf-
ficient for the installation of
the stern thruster a sloped
surface can be made to
install the stern thruster.
Than keep in mind that the
thrust tunnel must be pro-
tected against the forces
caused by the water flow
during normal cruising.
Installation in the bottom
of the vessel is not recom-
mended. The thrust tunnel
is not designed to with-
stand the forces of the
water flow during normal
cruising. At the same time
also the normal propul-
sion is highly slowed
down.
Installation of the flange
At the place of installation of the stern thruster attach the drill
pattern at the outside and mark the holes.
The drill pattern is on the centre
page.
IMPORTANT: The centerline of the drill pattern must be pre-
cisely horizontally and at least 150mm below the waterline.
For checking purposes drill first a small hole at the location of
the centre point of the flange. On the inside checking the avail-
able space for flange and motor can now be carried out easily.
Make the holes, depend-
ent of the material of the
ship's hull by means of a
drill and a jigsaw or with
an oxy-acetylene cutter.
Make sure that the holes
are free of burrs.
