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.
Claims12
A marine propulsion control system for a watercraft having a hull, a pair of propulsion units carried by said hull for propelling said watercraft, each of said propulsion units having a function control for controlling a specific function of the respective propulsion unit, a single moveable control element positioned within said hull, means for mechanically coupling said single moveable control element to each of said function controls for controlling the same function of each of said propulsion units, sensing means for sensing when the condition of the respective functions of the propulsion units being controlled do not correspond with each other, and means for altering the condition of one of the propulsion units to coincide with each other, and means for altering the condition of one of the propulsion units to coincide with that condition of the other propulsion unit.
