Positioning Of The Bow Thruster In The Thrust-Tunnel - Vetus BOW2512D Instructions De Montage

When choosing the location for the thrust tunnel, take the following into account for
optimum performance:
- The distance A shown in the drawing must be at least 0.5 x D (where D is the tun-
nel diameter).
- The length of the tunnel (distance B) should be between 2 x D and 4 x D.

Positioning of the bow thruster in the thrust-tunnel

When determining the exact position of the
bow thruster in the thrust tunnel, it should
be taken into account that the tailpiece may
NOT protrude from the tunnel end.
The propeller should preferably be situated
on the centreline of the vessel, but it must
always be accessible from the outside.
The electric motor can be installed in various
positions.
If the motor is installed horizontally, a sup-
port is absolutely necessary.
The electric motor must be positioned in
such a way that it is always well clear from
the maximum bilge water level.
