Marine propulsion inventions 05/06

20060110990 - Outboard motor steering control system: In an outboard motor steering control system having an actuator steering the outboard motor, three rotation angle sensors each detecting a rotation angle of a steering wheel, three steering angle sensors each detecting a steering angle of the outboard motor, and a controller determining a drive current to be supplied...

20060105642 - Boat propulsion system: A marine propulsion system may include at least one electric motor and a converter-fed electrical power supply. The at least one electric motor may be arranged in a propeller shaft pipe at a stern of a vessel for driving at least one vessel propeller, and may include at least one...

20060105643 - Marine engine stopping device: A device for shutting off or stopping a marine engine ignition system utilizing a transmitter for generating a wireless signal. The wireless signal is only generated upon association of the transmitter with a mass of water. A receiver acquires the wireless signal and generates a disconnection signal which interrupts the...

20060105644 - Amphibious vehicle: An amphibious vehicle (1), in the form of an inflatable boat (2) has a self propelled and steerable retractable undercarriage system, enabling the vehicle to enter and exit the water under its own power. The swing of the wheels and their supporting struts (3) & (4) occurs external to the...

20060105645 - Outboard jet drive marine propulsion system with increased horsepower: An outboard jet drive marine system for a boat comprising a housing. The housing is adapted to be affixed behind a hull of a boat. An engine is disposed within the housing. A jet drive unit is mounted to the housing in parallel to and vertically oriented to the engine,...

20060105646 - Drive apparatus: A drive apparatus (10) for propelling a vehicle across a body of water is described. The apparatus (10) comprises a prime mover, for example a gas turbine engine (12), and a propelling arrangement (26) driven by the prime mover for propelling the vehicle across the body of water and thereby...

20060105647 - Outboard motor control system: In an outboard motor control system having two outboard motors each mounted on a stern of a boat, there is provided a controller that controls operation of steering actuators to regulate steering angles of the outboard motors such that lines extending from axes of rotation of the propellers of the...

20060105648 - Boat and outboard motor having air intake system: A boat includes an outboard motor having an internal combustion engine enclosed within a cowling. The cowling has a rear inlet port for allowing outside air to be drawn into the cowling. A closure member selectively closes the inlet port depending upon a certain engine operating parameters. In another embodiment,...

20060099863 - Front-mounted water-separation propeller: Based on the law of dynamic water-separation, in this invention, a new type of front-mounted booster water-separation propeller has been designed to raise a vessel's speed by reducing resistance from water and increasing the advance force. It's composed of two parts, of which the external includes an influent tube (1),...

20060094310 - Powered surfboard: A motorized surfboard with substantially flat and smooth top and bottom surfaces, a maximum thickness of three inches or less and no protruding parts other than fins extending from a rear, bottom portion of the surfboard. The motorized surfboard is configured to perform in substantially the same manner as a...

20060094311 - Shift control mechanism for small watercraft: A shift control mechanism of a small watercraft for selectively shifting between a forward, a neutral and a reverse drive mode includes a first mounting bracket, a second mounting bracket, and a shift control lever having a grip for operating the shift control lever and first and second sides. The...

20060094312 - Generator set exhaust processing system and method: An exhaust processing device for implementation in a marine environment is disclosed. The exhaust processing device includes an inner tubular structure configured to receive exhaust gases from a generator set (genset) and communicate the exhaust gases therethrough. The exhaust processing device also includes an exhaust processing element mounted within the...

20060094313 - Oar saddle: A rowing frame is disclosed which, in the preferred embodiment, is adapted to mount on an inflatable boat. The frame can be disassembled and/or folded into a small package for storage, compatible with the deflated boat. The rowing frame assembles into a rigid configuration that mounts on the gunwales/side tubes...
