Positioning of the tunnel / thruster
MC_0003
Aim to install the thruster as far forward as possible (1)
Due to the leverage effect around the boats’ pivot point. The distance difference from the boat pivots’ point to the thruster will determine the amount
of real rotation power for the boat.
Aim to install the thruster as deep as possible under the waterline (2)
Deeper installations prevent air from being sucked into the tunnel from the surface, resulting in reduced thrust performance and increase noise levels
during operation. Deeper installations increase water pressure for maximum effi ciency from the thruster.
The centre of the tunnel should be a minimum of 1 x the tunnel diameter below the waterline. The installer must make evaluations based on thruster
performance, boat type and operating conditions. As a general recommendation, the position of the tunnel should not be a minimum of 1/4 of the
diameter of the tunnel from the boat keel. (NB: This can be overlooked depending on the installation methods defi ned in this manual.)
