A method controlling a thruster of a marine vehicle at least partially submerged in a liquid includes a body and a thruster including two propellers, each propeller including blades intended to turn about a rotation axis of said propeller, the method including a step of low-speed maneuver controlling, during which the thruster is controlled in such a way that each propeller generates a flow directed toward the flow generated by the other propeller and reaching the flow generated by the other propeller.
