Patent number: 9809290Abstract: An outboard motor mounting apparatus for outboard motors that control the outboard motor propeller thrust line angle of attack through a larger range than is currently available in practice today, including afterplanes (hydrodynamic lifting surfaces) in order to create boat stern lift. The afterplanes move to provide lift with a trimmable hinged portion in combination with movement of the outboard motor propeller thrust line.Type: GrantFiled: February 25, 2015Date of Patent: November 7, 2017Inventor: Kurt D. Willows

Patent number: 7143363Abstract: A method for displaying marine vessel information automatically selects a chosen visual display based on the magnitudes of one or more vessel-related parameters, such as engine speed, gear selector position, or vessel velocity. Based on the selected marine vessel operating condition, the chosen visual display is selected and the contents of that chosen visual display are presented on an information display device, such as a liquid crystal display or other type of monitor. As the marine vessel changes its operating condition, the process is repeated so that the marine vessel operator always is presented with the most appropriate screen images relating to the marine vessel at its current operating condition.Type: GrantFiled: July 25, 2002Date of Patent: November 28, 2006Assignee: Brunswick CorporationInventors: Phillip K. Gaynor, Kurt D. Willows

Patent number: 6885919Abstract: A process is provided by which the operator of a marine vessel can invoke the operation of a computer program that investigates various alternatives that can improve the range of the marine vessel. The distance between the current location of the marine vessel and a desired waypoint is determined and compared to a range of the marine vessel which is determined as a function of available fuel, vessel speed, fuel usage rate, and engine speed. The computer program investigates the results that would be achieved, theoretically, from a change in engine speed. Both increases and decreases in engine speed are reviewed and additional theoretical ranges are calculated as a function of those new engine speeds. The operator of the marine vessel is informed when an advantageous change in engine speed is determined.Type: GrantFiled: June 2, 2003Date of Patent: April 26, 2005Assignee: Brunswick CorporationInventors: John W. Wyant, Phillip K. Gaynor, Kurt D. Willows, Michael J. Lemancik

Patent number: 6511354Abstract: A multipurpose control mechanism allows the operator of a marine vessel to use the mechanism as both a standard throttle and gear selection device and, alternatively, as a multi-axes joystick command device. The control mechanism comprises a base portion and a lever that is movable relative to the base portion along with a distal member that is attached to the lever for rotation about a central axis of the lever. A primary control signal is provided by the multipurpose control mechanism when the marine vessel is operated in a first mode in which the control signal provides information relating to engine speed and gear selection. The mechanism can also operate in a second or docking mode and provide first, second, and third secondary control signals relating to desired maneuvers of the marine vessel.Type: GrantFiled: June 4, 2001Date of Patent: January 28, 2003Assignee: Brunswick CorporationInventors: Steven J. Gonring, Phillip K. Gaynor, Kurt D. Willows

Patent number: 6382122Abstract: An auto detect system is provided for a marine vessel in which the various associations and relationships between marine propulsion devices, gauges, sensors, and other components are quickly and easily determined. The system performs a method which automatically determines the number of marine propulsion devices on the marine vessel and, where needed, prompts the boat builder or marine vessel outfitter to enter various commands to identify particular marine propulsion devices with reference to their location on the marine vessel and to identify certain other components, such as gauges, with reference to both their location at a particular helm station and their association with a particular marine propulsion device.Type: GrantFiled: June 22, 2001Date of Patent: May 7, 2002Assignee: Brunswick CorporationInventors: Phillip K. Gaynor, Kurt D. Willows, John W. Wyant

Patent number: 5967866Abstract: A lower unit for a marine propulsion system has a flow disrupter positioned along the side wall of the vertical strut above the torpedo gearcase. The strut has a high pressure side and low pressure side which results from the strut being positioned at an angle with respect to the direction of boat travel in order to compensate for steering torque. The flow disrupter is positioned on the low pressure side of the strut, and promotes the separation of water passing over the vertical strut in a controlled manner, thereby reducing steering jerks during acceleration due to dramatic hydrodynamic flow changes. The flow disrupter consists of a series of steps or textured areas positioned along the aft section of the vertical strut. In a preferred embodiment, each of the steps contains a vent passage permitting exhaust to exit the strut through the steps to further promote controlled separation of water passing over the strut.Type: GrantFiled: December 2, 1997Date of Patent: October 19, 1999Assignee: Brunswick CorporationInventors: Kurt D. Willows, Timothy M. Fuhrmann

Patent number: 5816869Abstract: A propeller for a marine propulsion system that provides variable length exhaust paths depending upon the speed of the boat and motor. The propeller includes a propeller hub and an exhaust tube positioned within the propeller hub. The exhaust tube extends past the aft end of the propeller hub and defines a first exhaust passageway. A second exhaust passageway is positioned between the propeller hub and the exhaust tube. The second exhaust passageway is shorter than the first exhaust passageway. At low speeds, engine exhaust exits the longer first passageway, while at moderate speeds, engine exhaust exits the shorter second passageway. Therefore, the effective length of the exhaust path varies depending upon the speed of the motor, such that the length of the exhaust path is specifically tuned to several speeds of the motor.Type: GrantFiled: July 15, 1997Date of Patent: October 6, 1998Assignee: Brunswick CorporationInventor: Kurt D.
