Kill switch clip for a marine engine

Systems for maneuvering a marine vessel comprise an input device for requesting lateral movement of the marine vessel with respect to the longitudinal axis and a plurality of propulsion devices including at least a port propulsion device, a starboard propulsion device and an intermediate propulsion device disposed between the port and starboard propulsion devices. A control circuit controls orientation of the port and starboard propulsion devices inwardly towards a common point on the marine vessel, and upon a request for lateral movement of from the input device, operates one of the port and starboard propulsion devices in forward gear, operates the other of the port and starboard propulsion devices in reverse gear, and operates the intermediate propulsion device in reverse gear.

Marine vessels and systems for laterally maneuvering marine vessels

Systems and methods are for maneuvering a marine vessel having a plurality of steerable propulsion devices. The plurality of propulsion devices are controlled to achieve a lateral movement by controlling the steering orientation of port and starboard propulsion devices so that forward thrusts provided by the port and starboard propulsion devices intersect at or forwardly of a center of turn of the marine vessel. One of the port and starboard propulsion devices is operated to provide a forward thrust and the other of the port and starboard propulsion devices is operated to provide a reverse thrust so that the lateral movement is achieved and a resultant yaw component is applied on the marine vessel. An intermediate propulsion device is controlled to apply an opposing yaw component on the marine vessel that counteracts the resultant yaw component.

Systems and methods for monitoring the accuracy of a global positioning system (GPS) receiver in a marine vessel utilize a GPS receiver receiving a plurality of satellite signals, calculating a global position of the GPS receiver based on the plurality of signals, and determining a signal to noise ratio (SNR) of each signal in the plurality of signals; and a control circuit having a computer readable medium having executable code, and being connected to the GPS receiver by a communication link. The control circuit calculates an average SNR of the plurality of signals and compares the average SNR to a threshold SNR. In one example the threshold SNR varies depending upon a number of satellites sending the plurality of signals and a speed at which the marine vessel is traveling.

A method and system for monitoring a three-way catalyst cooled by a coolant and treating internal combustion engine exhaust by oxidizing HC and CO and reducing NOis provided to prevent false-fail monitoring. An initial lean kick excursion of fuel-air ratio Phi is provided prior to the first reducing step or interval of the first cycle.

Lean kick catalyst monitoring system

Systems and methods for maneuvering a marine vessel limit interference by the hull of the vessel with reverse thrust. A marine propulsion device provides at least a reverse thrust with respect to the marine vessel. The propulsion device is vertically pivotable into a trim position wherein the hull does not impede or interfere with the reverse thrust. A control circuit controls the propulsion device to move into the trim position when the reverse thrust of the propulsion device is requested.

Systems and methods for orienting a marine vessel enhance available thrust in a station keeping mode. A control device having a memory and a programmable circuit is programmed to control operation of a plurality of marine propulsion devices to maintain orientation of a marine vessel in a selected global position. The control device is programmed to calculate a direction of a resultant thrust vector associated with the plurality of marine propulsion devices that is necessary to maintain the vessel in the selected global position. The control device is programmed to control operation of the plurality of marine propulsion devices to change the actual heading of the marine vessel to align the actual heading with the thrust vector.

Systems and methods for orienting a marine vessel to enhance available thrust

Systems and methods for orienting a marine vessel minimize at least one of pitch and roll in a station keeping mode. A control device having a memory and a programmable circuit is programmed to control operation of the plurality of marine propulsion devices to maintain orientation of a marine vessel in a selected global position and heading. The control device receives at least one of actual pitch and actual roll of the marine vessel in the global position and controls operation of the plurality of marine propulsion units to change the heading of the marine vessel to minimize at least one of the actual pitch and the actual roll while maintaining the marine vessel in the selected global position.
