Abstract
A power splitting gearbox is provided that allows a single prime mover to distribute power, for example torque, to multiple final drive assemblies, such as surface drives or other final drives. The power splitting gearbox can be provided downstream from a marine transmission and can be mounted directly to a transom of a marine vessel. The gearbox can have a back wall that accepts and supports mounting surfaces of the multiple final drive assemblies such that the gearbox bears the weight of the multiple final drive assemblies. The gearbox has two outputs that rotate in opposing directions so that a pair of final drive assemblies mounted to the gearbox will counter-rotate a pair of propellers for providing a propulsive force that moves the marine vessel.
