ABSTRACT:
An improved propulsion unit control system for marine units having at least two propulsion systems. A single lever control controls the speed of both propulsion systems and if a difference in speed occurs, the speed of the faster propulsion unit is reduced. In addition, each propulsion unit includes a respective abnormal condition sensor which outputs a signal to a common control system. This common control system reduces the speed of both propulsion units when an abnormal condition is sensed in either unit.
