The current manufacturing practice in the recreational boating industry is to align and couple a singular inboard engine to a singular impeller drive. The disclosed invention is a power transmission device that allows for coupling of a singular engine to one or more impeller drives. The invention can provide a single engine watercraft with the advantages of a twin-engine watercraft, but at half the complexity and half the weight of a twin-engine installation. The present invention can also be employed for the installation of a larger high performance engine while powering standard low cost impeller drives, and without fear of loss in reliability, or even in a multiple fashion, within a multi-engine watercraft, allowing for various options such as closer placement of the impeller drives without the staggering of engines.
