20080124989 - Marine propulsion shift control: A marine propulsion system that utilizes a transmission shift sequence to control shifting of the propulsion system transmission between forward and reverse gears. The marine propulsion system includes a controller that executes the transmission shift sequence using engine speed and transmission fluid pressure signals to determine the timing of various... Agent: James D. Stevens Reising, Ethington, Barnes, Kisselle, P.C.

20080119094 - Watercraft steering system, and watercraft: A watercraft can have an electric motor mounted on a screw bar extending in a right/left direction. The electric motor can move along the screw bar in the right/left direction to steer an outboard motor, or another part of a different marine propulsion system. One or more springs can be... Agent: Knobbe Martens Olson & Bear LLP

20080119095 - Outboard motor control system: In a system for controlling outboard motors each mounted on a boat and each having an engine, a steering mechanism, a shift mechanism, an actuator driving at least one of the steering mechanism, the shift mechanism and a throttle valve of the engine, and a controller controlling operation of the... Agent: Carrier Blackman And Associates

20080119096 - Boat steering system: A steering system for a boat with three or more propulsion units allows the operator to operate the boat in the same manner before and after a failure of one of the propulsion units. The steering system includes not more than two control levers to control three or more propulsion... Agent: Knobbe Martens Olson & Bear LLP

20080113569 - Control apparatus for hybrid type outboard motor, marine vessel running support system and marine vessel using the same: A hybrid type outdoor motor includes a propeller, an electric motor that generates a drive force to rotate the propeller, and an engine that generates a drive force to rotate the propeller. The engine discharges exhaust gas in water. A control apparatus that controls the hybrid type outboard motor includes... Agent: Yamaha Hatsudoki Kabushiki Kaisha C/o Keating & Bennett, LLP

20080113570 - Control apparatus for outboard motor, and marine vessel running support system and marine vessel using the same: The control apparatus controls an outboard motor having a propeller and an engine that rotates the propeller and discharges exhaust gas in water. The control apparatus includes a judgment unit arranged to determine a reduction in the propulsive force of the outboard motor due to in-water exhaust of the engine,... Agent: Yamaha Hatsudoki Kabushiki Kaisha C/o Keating & Bennett, LLP

20080113568 - Watercraft speed control device: An automatic speed control system that provides desired watercraft velocity over land. The coupled algorithms correct engine speed and torque using inertia based measurements, GPS, and tachometer measurements, and the corrections are augmented and enhanced by velocity/speed and torque/speed relationships that are dynamically and adaptively programmed with real-time data collected... Agent: Jackson Walker, L.l.p.

20080113571 - Outboard motor steering assembly with rudder reference sensor: An outboard motor having a steering control and a rudder reference sensor, both connectible to a computer-operated guidance system, The steering control utilizes a linear actuator connected through a linkage to the motor. The actuator utilizes a rack that moves along the axis about which the motor pivots from its... Agent: Howson And Howson

20080108256 - Boat steering system: An outboard motor is provided on a hull and a steering system is connected electrically to the outboard motor and adapted to steer the hull by rotating the outboard motor. Steering motors are provided to the outboard motor. A control unit has a motor selector for choosing which of the... Agent: Knobbe Martens Olson & Bear LLP

20080108257 - Amphibian: The present invention provides, with reference to FIG. 1, an amphibian for use in land and marine modes comprising: a planing hull; three wheel stations, two of the three wheel stations being front wheel stations provided one on each side of and in the front half of the amphibian, and... Agent: Fulwider Patton LLP

20080102718 - Shift mechanism of outboard motor: An outboard motor includes an engine vertically supporting a crankshaft above an engine holder and a shift mechanism switching a rotational direction of a propeller shaft by actuating a shift apparatus through a remote control from a shift lever. The shift mechanism includes a first link mechanism connecting a shift... Agent: Barnes & Thornburg LLP
