A control system for a steerable thrusting device is disclosed comprising a mobile device and application which interface with an electronic controller to command the output power and directional heading of the steerable thrusting device. In at least one embodiment, the mobile device serves the functions of a mapping and input device that communicates bi-directionally with a Global Navigation Satellite System (GNSS) and direction device-equipped electronic controller, which in turn controls the power and heading of the thrusting device on a marine vessel. Data can be stored on the mobile device or procured in real-time via network access to a dedicated database and communicated to the electronic controller in order to execute specific functions of the thrusting device control system. The data created in the control system is capable of being shared amongst similar devices via the use of a cloud network.
