The utility model relates to the field of propulsion systems of harbor tugs, in particular to an electric tug with an L-shaped steering oar propulsion system, which comprises a permanent magnet synchronous motor, a vertical shaft, a bevel gear set and a propeller. An output shaft of the permanent magnet synchronous motor is coaxially connected with the vertical shaft in the vertical direction, and the lower end of the vertical shaft is connected with a rotating shaft of the propeller through a bevel gear set. The electric tugboat with the L-shaped steering oar propelling system is provided with the vertical main propelling motor and the L-shaped steering oar propelling system, so that the space of a ship length is not additionally occupied any more, comprehensive arrangement of other large-scale equipment and a cabin of the large-scale equipment is facilitated, and the difficulty of total arrangement design within the limited ship length is reduced; the whole structure of the steering oar transmission system
