The invention relates to a motorization system for an electrically assisted craft which is intended to allow a user to be transported on water, the invention being used particularly in the field of surfboards, paddleboards or sailboards, and in the field of kayaks or canoes.The electric motorization system is configured to be connected to an electrical energy source and comprises, on the one hand, a watertight enclosure 1 which is intended to be integrated in or on a craft, in which enclosure 1 a rotor 2 and a stator 3, 7 are arranged, and, on the other hand, a shaft 4 which is connected at a first end to the rotor 2 and which protrudes in a watertight manner outside the enclosure 1 at a second end opposite its first end. The shaft 4 can be connected at its second end to propulsion means of a craft, such as a propeller, so that when the system is supplied with electrical energy, the rotor 2 is rotated and drives the shaft 4 with this rotation.The system also comprises cooling means 5 which themselves comprise at least one first elongate assembly 5, which is at least partially made of metal, and a first end of which is arranged inside the enclosure 1, the elongate assembly 5 protruding in a watertight manner outside the enclosure 1 at a second end opposite its first end so as to allow conduction of the heat from the inside to the outside of the enclosure 1 along the first elongate assembly 5.
