Tunnel Thruster

*Tunnel bow thrusters are highly cost effective and easy to fit on many boat types. When installed at the correct immersion depth and using the shortest tunnel length possible, tunnel thrusters offer an ideal solution for motor boats and even deep-footed sailing yachts when sailing performance is not paramount.

* Thrusters are designed to run at 10.75V on 12V units and 22V on 24V units. Higher voltages will result in higher thrust ratings, higher power consumption, and a reduced duty cycle.

* Performance data is given for a thruster installed at an immersion depth of one tunnel’s diameter, in a tunnel no longer than twice the tunnel’s diameter, and this within a variation of + / - 6%. Longer tunnels will result in lower thrust ratings and higher power consumption.
