[Problem] An object of the present invention is to provide a boat propulsion system and a method for controlling a boat propulsion unit in which a boat can be effectively made to move laterally on the basis of an operational command provided by an operation portion in a boat equipped with at least four propulsion units. [Solution] A control unit individually controls the forward and reverse propulsion directions, the propulsion force, and the steer angle of the plurality of boat propulsion units so that a point of action of a first resultant force is positioned behind a point of action of a second resultant force when the control unit receives a operational command for operation in the lateral direction from the operation portion. The first resultant force is the resultant force of propulsion force generated by the first port-side propulsion unit and the first starboard-side propulsion unit. The second resultant force is the resultant force of propulsion force generated by the second port-side propulsion unit and the second starboard-side propulsion unit.
