Tunnel 2thrusters are easy to install and provide a cost-effective solution to enhance the manoeuvrability of your boat. Tunnel thrusters are therefore often used as standard thrusters on motor boats and sailing yachts.
When installed in the right position, high thrust efficiency is ensured, making them the ideal solution for motor boats as well as sailing yachts – the closer the tunnel is to the bow of the boat, the greater the torque and efficiency of the thruster. All GME thrusters are designed in such a way that they can also be used for stern propulsion.



The following selection table should help you make your initial choice from the range of GME tunnel thrusters available.


The ultimate manoeuvrability of the boat is determined by the thrust of the actual bow propeller rather than the kilowattage or horsepower of the electric or hydraulic power source.
GME bow propellers have an extremely high rated thrust as they are built with top quality bearings, gears and propellers boasting a large blade area and optimum blade design.
