The invention relates to a driving unit for an electric tunnel thruster. Such driving unit comprises an electric motor (1) with a shaft (2), an electric motor support (3) to be mounted on a tunnel (4) of the electric tunnel thruster and a driving unit transmission with reduction gear ratio >1 for transmitting of electric motor rotation to an L-shaped transmission (8) of the propeller (9). The driving unit transmission can be a gear transmission, such as a planetary gear reducer (11). Said planetary gear reducer can be fully or partially embedded in a cavity of the front flange (18) of the motor (1). The advantages of the electric tunnel thruster, according to the present invention, are the small vertical dimensions, the option to use a cheaper motor with less torque and a cheaper/smaller L-shaped redactor also allowing more water to flow through the tunnel cross-section.
