Upon generation of the lanyard event, the propulsion device is controlled to reduce an engine RPM to an idle RPM or the propulsion device is turned off.

Abstract: A remote control system for a marine vessel includes at least one fob communicating with a helm transceiver module on the vessel. The fob has at least two user inputs, each associated with a different user-selectable fob command, wherein the fob is configured to wirelessly transmit a fob identification and a selected fob command in response to user selection of a user input. The helm transceiver module is configured to store unique fob identifications for permitted fobs and a set of system commands for each user-selectable fob command for each fob identification, wherein the set of system commands are configurable by a user. Upon receipt of the fob identification and the selected fob command, the helm transceiver module verifies that the fob identification is associated with one of the permitted fobs and identifies the user-configured set of system commands associated with the selected fob command and the fob identification.

Abstract: A method for controlling a course of a marine vessel powered by a marine engine as it moves in a body of water includes determining a current global position and a current heading of the vessel and initiating an auto-waypoint mode of a vessel course control system.

The method thereafter includes automatically rotating a steerable component coupled to the vessel and rotatable to affect a direction of movement of the vessel so as to counteract external forces on the vessel and thereby to maintain the vessel's set course.

Abstract: A system for controlling steering and thrust of a marine vessel's propulsion device includes a joystick assembly providing input signals to a control module. The joystick assembly includes a docking station at the helm; a first electrical connector in the docking station cable-connected to the control module; a detachable base for coupling with the docking station; a handle moveable within the detachable base to generate the input signals; a second, complementary electrical connector in the detachable base; and a wireless transmitter mounted in the detachable base. A wireless receiver communicates with the transmitter and the control module. When the detachable base is coupled to the docking station and the electrical connectors are mated, the cable transmits input signals to the control module. When the detachable base is removed from the docking station and the electrical connectors are disconnected, the wireless transmitter and receiver transmit input signals to the control module.

The rigging system includes a plurality of engine-sourced lines extending from an engine of the outboard motor, through an aperture in the motor housing, and to the marine vessel. A protective tube surrounds the plurality of engine-sourced lines and has a first end coupled to the motor housing and a second end coupled to the marine vessel.

A crankshaft is caused to rotate by the first and second banks of piston-cylinders. A flywheel is coupled to the upper end of the crankshaft such that rotation of the crankshaft causes rotation of the flywheel. An alternator is located above the cylinder block and coupled to the flywheel such that rotation of the flywheel operates the alternator.
