Patent number: 8468964Abstract: Methods and arrangements to redirect a forward thrust generated by a propeller of a watercraft to provide a non-forward thrust are disclosed. More specifically, embodiments comprise a control surface to redirect the forward thrust from the propeller.

For instance, by adjusting the amount of prop wash hitting the control surface, the magnitude of the redirected thrust from the control surface can be adjusted. Further, adjusting the angle of the control surfaces adjusts the direction as well as magnitude of a reverse thrust component. The net thrust can be in any direction and rotational.Type: GrantFiled: September 13, 2005Date of Patent: June 25, 2013Inventors: Kevin Daniel Hoberman, Steven Clay Moore

In other embodiments, mechanical cable, fluidic, or electrical control systems are used to control the configuration of the support bar mechanism.Type: ApplicationFiled: March 30, 2010Publication date: October 7, 2010Inventor: Roger J.

Patent number: 7677938Abstract: A tiller arm pivotably mountable to a marine outboard engine about a pivot axis is described. First and second arms extend away from the pivot axis. A middle portion has a first end attached to the first and second arms. A handle portion extends away from the second end of the middle portion in a direction away from the pivot axis. A throttle grip is rotatably mounted to the handle portion and rotatable with respect thereto about a throttle grip axis generally perpendicular to the pivot axis. The throttle grip is operatively connectable to the marine outboard engine. The width of an aperture defined by the arms and the middle section is greater than the widths of the throttle grip and the first and second arms.Type: GrantFiled: October 31, 2008Date of Patent: March 16, 2010Assignee: BRP US Inc.Inventors: Darrell Wiatrowski, Peter Lucier, Pierre Vignau

Publication number: 20090227158Abstract: A mount for securing a trolling motor to a watercraft has a base, a main arm, a motor coupling, and a linkage. The motor coupling is configured to rotatably retain the trolling motor. The main arm is pivotally coupled to the base. The linkage is pivotally coupled with the base and the main arm and extends within the main arm to contact the motor coupling for actuating rotation of the motor coupling between a first position when the main arm is in a stowed position, and a second position when the main arm is in a deployed position.Type: ApplicationFiled: March 4, 2008Publication date: September 10, 2009Applicant: Johnson Outdoors, Inc.Inventors: Darrel A.

Patent number: 7585195Abstract: A propulsion and steering unit for a waterborne vessel. The propulsion and steering unit is in the form of an azimuth thruster 1 comprising a propeller 2 fixed to one end of a propeller shaft 4, which is rotatable about a longitudinal axis 6. Fixed to the other end of the propeller shaft 4 there is a beveled gear crown wheel 8. The crown wheel 8 is engaged with a driving pinion gear 10 and, in this particular embodiment, the crown wheel 8 is driven in a direction 7 by the driving pinion gear 10. The driving pinion gear 10 is mounted on a vertical drive shaft 12, which is connected to drive means (not shown) for the vessel. A longitudinal axis 18 of the drive shaft 12, about which the drive pinion 8 rotates, is substantially perpendicular to the longitudinal axis 6 of the propeller shaft 4 about which the propeller 2 rotates.Type: GrantFiled: April 11, 2007Date of Patent: September 8, 2009Inventor: Leif Vartdal

Publication number: 20090142974Abstract: A steering connecting device for a boat couples the steering of a primary propulsion device and an auxiliary propulsion device. The primary propulsion device has an outer surface and is attached to the transom of the boat and an auxiliary propulsion device. There is a hinge assembly hingeably attached to and essentially parallel to the transom of the boat. There is a mounting plate fixedly attached to the hinge assembly. A tie rod is rotatably attached at a first end to the outer surface of the primary propulsion device and rotatably attached at a second end to the mounting plate. The auxiliary propulsion device is rigidly attached to the mounting plate. As the primary propulsion device is rotated from left to right during steering of the boat, the mounting plate also rotates from left to right thereby rotating the auxiliary propulsion device in unison with the primary propulsion device.Type: ApplicationFiled: December 4, 2007Publication date: June 4, 2009Inventor: Wesley M. Strobel

Patent number: 7527537Abstract: A steering device can include a steering wheel, connecting members for connecting outboard motors together, and a plurality of steering motors for steering a plurality of outboard motors. A target steering angle setting device can be configured to obtain a steering angle according to a steering displacement of the steering wheel, and steering unit angle sensor can be configured to detect actual steering unit angles of the respective outboard motors. A correcting device can be configured to obtain the difference between actual steering unit angles of the outboard motors, to correct the target steering angles based on the difference, and to obtain a target steering angle of each of the outboard motors. Motor controlling device can be configured to control the steering motors so that a target steering angle agrees with the actual steering unit angle for each of the outboard motors.Type: GrantFiled: November 6, 2006Date of Patent: May 5, 2009Assignee: Yamaha Hatsudoki Kabushiki KaishaInventor: Makoto Mizutani

Patent number: 7510450Abstract: A trolling motor is provided with an over-center clamping mechanism that facilitates its connection to a transom of a marine vessel. First and second clamping elements move toward or away from each other in response to manual manipulation of a handle. The use of an over-center mechanical arrangement allows quick and reliable attachment and removal of the clamping mechanism from the transom.Type: GrantFiled: November 19, 2007Date of Patent: March 31, 2009Assignee: Brunswick CorporationInventor: Joshua L.
