One feature of the throttle control system is twist-style grip that has an axis with an angle adjustable to a housing. Another feature comprises trim and/or outboard motor control(s) atop the grip. Yet another...

20060189227 - Paddle wheel propulsion system and improved paddle used therewith: A paddle wheel propulsion system includes a paddle wheel mounted for rotation about its horizontal axis for propelling a vessel, and for unlimited rotation about a vertical axis perpendicular to its horizontal axis for steering the vessel. The paddle wheel is also supported for limited vertical movement relative to the...

20060183384 - Amphibious vehicle suspension: A retractable suspension for an amphibious vehicle, the configuration of which allows the size of an opening in the hull necessary for accommodating the protraction of each wheel to be kept to a minimum. The suspension is configured such that the only component that comes to extend beyond the hull...

20060183385 - Pivoting footrest for rowing boats: A spring loaded pivoting footrest for a rowing boat....

20060183386 - Outboard motor having seal structure for exhaust release pipe: An outboard motor includes an elastic seal lid attached to an under cover to form a hermetic seal between the under cover and an exhaust release pipe while closing an opening of the under cover from which an outlet portion of the exhaust release pip projects outwardly. The seal lid...

20060178058 - Vehicle steering arrangements: A vehicle steering arrangement for an amphibious vehicle having retractable steered wheels with which the steering input to such wheels is automatically substantially curtailed upon retraction of the wheels. Retraction of the wheels causes a steering link to swing toward its steering axis to thereby reduce its effective radius while...

20060178059 - Propulsion system for and amphibious track driven vehicle: A propulsion system for amphibious track driven vehicles. The propulsion system includes a driven track having for example paddles extending therefrom and supported by a suspension framework. The track is driven by drive cogs of for example plastic or metal. A manifold partially encloses the track and includes a water...

20060178060 - Propeller shaft apparatus: A paper tube of a propeller tube 12 is made by winding a single faced corrugated fiberboard 16 in which a wavy corrugating medium 16b is fixed to one side of a flat linerboard 16a so that the corrugating medium 16b is oriented outwards, and the corrugating medium 16b contacts...

20060172625 - Linear propulsor with linear motion: The invention comprises a scalable, configurable “propulsor” system. A propulsor system is an assembly of individual propulsors that act in concert to form a substantially continuous control surface that undulates in a working fluid. Each propulsor is driven and configured by computer-controlled actuators so that the control surface undulates in...

20060172627 - Amphibious vehicle: A planing amphibious vehicle with retractable wheels and a sit-astride seat having dimensions that impart enhanced capability in both land as well as water modes of operation. The beam, track, dead rise angle and the location of the handlebars cooperate to enhance freeboard and ground clearance without sacrificing manoeuvrability. The...

20060172626 - Amphibious vehicle speed change transmission arrangement: A power train configuration for an amphibious vehicle especially well suited for sit-astride applications. A prime mover drives a marine propulsion unit and/or at least one road wheel wherein the such road wheel is driven through a speed-change transmission. The speed-transmission is positioned above or below the axis of the...

20060172628 - Amphibious vehicle transmission: An amphibious vehicle has retractable road wheels to allow planing over water. Power to the road wheels is disconnected automatically as the wheels are retracted. This may be achieved through a cable attached to a suspension rocker arm to disconnect a dog clutch attached to the input shaft of a...

20060172629 - Linear propulsor with radial motion: The invention comprises a scalable, configurable “propulsor” system. A propulsor system is an assembly of individual propulsors that act in concert to form a substantially continuous control surface that undulates in a working fluid. Each propulsor is driven and configured by computer-controlled actuators so that the control surface undulates in...

20060172630 - Marine vessel propulsion structure and marine vessel driving apparatus: In an outboard drive or an inboard-outboard drive, power generated by a single engine is transmitted in left and right directions from a main drive shaft, thereby finally causing left and right propellers to be rotated, the left and right propellers being arranged about the main drive shaft so as...

20060172631 - Outboard motor: An outboard motor has a cowling comprising a top cowl that is removably engagable with a bottom cowl. A mating portion of the top cowl and the bottom cowl is sealed when the top and bottom cowls are engaged so as to prevent or inhibit water from entering the cowling...

20060172632 - Arrangement in a propulsion system: In a counter rotating propulsion system (CRP), whereby the aft propeller (22) and the forward propeller (6) have opposite directions of rotating and the aft and forward propellers are arranged against each other, the forward propeller is provided with a hubcap (30), wherein at least two equally distributed flow plates...

20060172633 - Method of using a linear propulsor array for propulsion & navigation: The invention comprises a method of using a scalable, configurable “propulsor” system to move and navigate a submersible device through a fluid medium. A propulsor system is an assembly of individual propulsors that act in concert to form a substantially continuous control surface that undulates in a working fluid. Each...
