    Abstract: A marine vessel includes a hull, an operator station having an operator interface configured to receive a mode input and a lever position input, a left propulsion system, a right propulsion system, and a control module. Each of the propulsion systems includes an engine, a transmission, a troll valve configured to adjust clutch slip, a shaft, a shaft speed sensor configured to detect the speed of rotation of the shaft, and a propeller. The control module is configured to receive the mode input and the lever position input from the operator interface, receive signals from the left shaft sensor indicating a left shaft speed, receive signals from the right shaft sensor indicating a right shaft speed, determine if the vessel is operating in a trolling state, and determine if a sync mode is active, based on the mode input. If the sync mode is active and the vessel is in a trolling state, the speed of the left shaft and the right shaft are synchronized.

    Abstract: A marine propulsion control system for use with a marine vessel, includes a port side engine in electronic communication with a port side engine controller and a starboard side engine in electronic communication with a starboard side engine controller. A control station includes a port lever configured to control a throttle of the port side engine, a starboard lever configured to control a throttle of the starboard side engine, and a user interface. A propulsion control processor is in electronic communication with the port side engine controller, the starboard side engine controller, and control station. In a synchronized operating mode, the propulsion control processor transmits a throttle instruction to the port side engine controller and the starboard side engine controller pursuant to a throttle position of a master lever corresponding to the first of the port lever and starboard lever to be actuated upon activation of the synchronized operating mode.

    IPC: B63H21/21

    Abstract: An advanced control station system for a marine vessel. The control station provides a motor-controlled lever head with the ability to control the amount of pressure required to move the lever head as well as the ability to set adjustable detents within the range of motion of the lever head. The advanced control station further provides for electronic communication between multiple stations controls so that the throttle and transmission settings from one control station can be synchronized during a control station transfer.

    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.

    Abstract: A first method of protecting an engine and a transmission of a marine vessel during gear shifts and a second method of programming one or more Shift Protection Sequences (SPS) are disclosed. The first method includes receiving a Shift Request (SR) and activating a SPS from among a plurality of enabled SPS. The second method includes configuring a Shift Protection Type (SPT); enabling and configuring a plurality of required and SPS variables; and, optionally, enabling and configuring a plurality of optional SPS variables. The SPT may be a Basic Shift Protection (BSP), which includes time-based SPS; or the SPT may be an Advanced Shift Protection (ASP), which includes alternate time-based and operating-variable based SPS. The SPS of the ASP may be incrementally programmed and added to the BSP.
