INSTALLATION
• 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 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 contrasting the propeller thrust.
The vertical mesh prevents the entry of most of the floating objects.
