1. A propulsion system (30) intended to be integrated into a boat (1) and comprising:
a) A vertical guide device (31) comprising a member for fixing the vertical guide device (31) to the hull of said boat (1);
b) An electric thruster (32) comprising a gyration box (33), said gyration box (33) being vertically movably mounted on the vertical guide device (31) to be able to adopt an emerged position and a submerged position, wherein the electric thruster (32) rotates when moving from the submerged position to the emerged position or vice versa, said electric thruster (32) is rotatably mounted on the gyration box (33) along a vertical axis (V);
c) A drive system (34) capable of causing a vertical movement of the gyration box (33) of the electric thruster (32) along the guide device (31);
d) A control unit (35) capable of receiving a movement instruction and arranged, in response to said instruction, to control the drive system (34) to cause movement of the gyration box (33) toward the emerged position or toward the submerged position; and
wherein the drive system (34) is able to cause rotation of the thruster (32) about said vertical axis (V), and wherein the control unit (35) is arranged, in response to said instruction, to control the drive system (34) to cause rotation of the thruster (32) toward the emerged position from the submerged position or vice versa according to said instruction.
