A propulsion unit control system is provided for a boat having plural propulsion units provided side by side and electrically connected in association with two adjacent operation levers. The control system synchronizes engine speeds of the respective propulsion units with each other in light of inputs to the two operation levers. The control system computes a deviation between the averaged engine speed of a reference propulsion unit and the averaged engine speed of a propulsion unit to be synchronized, and corrects a throttle opening of the propulsion unit to be synchronized based on the computed deviation in order to synchronize the engine speeds of the respective propulsion units with each other.
