The vessel further includes an upper driveshaft disposed above the waterline, an engine disposed within the hull including an engine drive shaft, and a transmission shaft. The ... 08/03/06 - 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 ... 07/27/06 - 20060166573 - Drive system for a marine vessel A drive system for a marine vessel. The drive system includes a drive shaft that is rotatable about a drive axis and a motor interconnected with the drive shaft and including a rotor that defines a motor axis that is substantially coaxial with the drive axis. The motor is operable ... 07/27/06 - 20060166572 - Power train of a marine transport vessel Propellers of a marine transport vessel may be independently controlled at their optimal speed when at least one transmission having a plurality of output shafts capable of independent-speed ratios is connected to an engine and the propellers are respectively mounted at the output shafts of the transmission. ... 06/01/06 - 20060116034 - Outboard drive with speed change mechanism An outboard drive includes a prime mover having an output shaft. A driveshaft is coupled with the output shaft. Both shafts having axes that extend at least generally parallel to each other. A propulsion device is coupled with the driveshaft. The prime mover rotates the output shaft to drive the ... 04/27/06 - 20060089062 - Power boat drive system with multiple gearboxes A boat drive system is provided for a power boat which includes an engine having a drive shaft, connected to a pair of propeller shafts. The drive system includes a primary gearbox and opposed outboard gearboxes. The primary gearbox includes a housing and a gear arrangement connected to the engine ... 04/06/06 - 20060073747 - Marine reversing gear assembly The present invention provides a marine reversing gear assembly, wherein a manual directional control valve 7a and an electromagnetic directional control valve 7b for a forward/reverse directional control valve 7 for hydraulic oil supply circuit 10 have a common structure of an oil line joint surface for the hydraulic oil ... 03/02/06 - 20060046584 - Transmission set for motorboats A transmission set for planing motorboats, comprising a fixing bracket (16) which at the same time allows to firmly block the containing box linked and engaged to the stern of the hull, in an absolutely invariable position: said bracket (16) is provided with two longitudinal arms placed in such a ... 08/04/05 - 20050170715 - Shift operation apparatus for outboard motor, electronic remote control apparatus for medium-sized boat, and engine control apparatus A shift operation apparatus for an outboard motor of the present invention comprises a case fixed to an outboard motor, a motor provide at the case, a worm gear which is rotated by the motor, a worm wheel engages with the worm gear, an output shaft provided so as to ... 07/21/05 - 20050159054 - Marine jet propulsion arrangement A jet propulsion arrangement, including a jet propulsion unit (32) having a housing (38) which includes an inlet (40) through which liquid is received, an outlet (34) through which liquid is discharged, a liquid path (39) between the inlet (40) and the outlet (34) and an impeller (41) disposed in ... ### FreshPatents.com Support |
