Abstract : This patent application discloses an invention which relates to dual propeller drive systems and more particularly to device for converting a single drive shaft to a multi-propeller system. This multi-propeller drive system has a single input shaft for connect to an engine system, a differential gear assembly. The differential gear assembly operates in a manner wherein one output shaft, if required, is permitted to resolve at a different rate than the other output shaft. A pair of brake mechanisms acting on the output shafts of the differential gear assembly enables an operator to control the rotational speed of the respective propellers without modifying the engine speed or transmission settings
