Abstract:
A marine propulsion control system for use with a marine vessel includes an engine in electronic communication an engine controller, and a transmission having a gearbox and an oil pressure sensor in electronic communication with the engine controller and configured to measure a transmission oil pressure. The gearbox includes a feedback sensor configured to transmit a gear state. A propulsion device is rotatably connected to the gearbox, and a shaft fixedly attached to the propulsion device and rotatably coupled to the gearbox. The shaft includes a shaft rotation sensor configured to measure a rotational direction of the shaft. A propulsion control processor is in electronic communication with the engine controller, the shaft rotation sensor and the gearbox, and is configured to determine a current gear of the marine vessel based on the rotational direction of the shaft and one or more of the gear state and the transmission oil pressure.
