Agent: Olson & Cepuritis, Ltd.

20090124142 - High water-speed tracked amphibian: An amphibious vehicle capable of high speeds on the water has a buoyant hull with driven tracks on each side of the hull. The tracks are movable between an upper position and a lower position relative to the hull. The tracks propel the vehicle both for land travel and water... Agent: Bracewell & Giuliani LLP

20090124144 - System for steering and maneuvering a watercraft propelled by a water jet: A system for steering a watercraft propelled by a water jet includes a control lever supported to pivot rightward and leftward about a first axis, a nozzle supported on the watercraft to pivot rightward and leftward and through which water is discharged from the watercraft, first and second cables, and... Agent: Macmillan Sobanski & Todd, LLC

20090124145 - Marine drive system with partially submerged propeller: A marine drive system (1) with a partially submerged propeller located at the transom of a boat comprising, for each propeller (2), a forward-opened shroud (20), positioned above the propeller (2), such as to define, between it and the water level, a channel (23) extending longitudinally and having, at the... Agent: Nixon & Vanderhye, PC

20090124146 - Ship propulsion unit and ship propulsion method: The invention relates to a ship propulsion unit with drive devices in the hull and all underwater pod, which is located outside of the hull and which has a front propeller and a rear propeller as well as torque transmitting devices between the drive devices and the propellers. The torque... Agent: Fleit Gibbons Gutman Bongini & Bianco Pl

20090117788 - Marine vessel running controlling apparatus, and marine vessel including the same: A marine vessel running controlling apparatus is applicable to a marine vessel which includes a propulsive force generating unit, a steering unit, and an operational unit to control a steering angle. The marine vessel running controlling apparatus includes a target characteristic storage unit arranged to store a target characteristic line... Agent: Yamaha Hatsudoki Kabushiki Kaisha C/o Keating & Bennett, LLP

20090117789 - Engine for driving a watercraft propelled by a water jet: A system for driving a water induction and discharge system of a watercraft propelled by a water jet includes a water impeller, an engine including a driven shaft and a first chamber for containing engine oil, a second chamber for containing engine oil, a pinion secured to the driven shaft...
