BOW THRUSTER BTQ250 - BTQ300 IT GB - REV002A
• The rounded ends of the tunnel prevent the creation of turbulence and cavitation, improving performance of the pro-
peller thrust and reducing noise levels to a minimum.
• The force produced by the fl 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 fl ow.
To limit this phenomenon, prepare an indentation in the rear part of the tunnel. Otherwise, create a defl ector on the
front part of the tunnel.
• If the tunnel is near the waterline, it is advisable to fi t a grating at the
end of the tube.
The grating must have as large a vertical mesh as possible to avoid
contrasting the propeller thrust. The vertical mesh prevents the entry of
most of the fl oating objects.
