20100248561 | HYBRID OUTBOARD MOTOR - There is provided a hybrid outboard motor capable of transmitting motive power of a power source appropriately and efficiently in a limited space while achieving compactness, high performance, and the like. The hybrid outboard motor includes: a casing; a power unit housed in the casing; a screw disposed outside the casing, the screw being driven by the power unit; a power transmission system transmitting motive power of the power unit to the screw; an internal combustion engine and an electric motor serving also as a generator, the internal combustion engine and the electric motor being arranged in parallel in a beam direction in the casing; and a first clutch disposed between the internal combustion engine and the electric motor, wherein one or both of the internal combustion engine and the electric motor are connected to a propulsion unit including the screw so as to rotate it. | 09-30-2010 |
20100248562 | HYBRID OUTBOARD MOTOR - A power unit is housed in a casing, and a screw (propeller) is disposed outside the casing, the screw being driven by the power unit. The casing is formed as a watertight case in a substantially rectangular parallelepiped shape with a left-right width direction being a longitudinal direction, and the case has at least a front face portion coupled to a stern portion and a substantially flat upper face portion at a substantially same height as a top portion of the stern portion. | 09-30-2010 |
20110244738 | ELECTRIC OUTBOARD MOTOR - In an electric outboard motor to be driven by an electric motor, the electric motor is formed in a watertight manner and is disposed to be exposed to the outside. Further, the electric motor is an air cooled type, and a shape of the electric motor is in a substantially flat shape in which a dimension in a horizontal direction perpendicular to an output shaft of the electric motor is made larger than a dimension in a height direction. The electric motor, when a hull is seen in plan view, is disposed in a manner that a front portion of the electric motor overlaps a transom board of the hull at the rear. | 10-06-2011 |
20110244739 | ELECTRIC OUTBOARD MOTOR - An electric outboard motor to be driven by an electric motor separately includes an electric outboard motor main body including the electric motor and a propulsion section that applies the electric motor as motive power and a power supply section supplying power to the electric motor, in which the electric outboard motor main body and the power supply section are detachably connected by couplers via a cable. Further, the coupler of the cable is allowed to be attached and detached to and from the coupler on a side of the power supply section. | 10-06-2011 |
20110244740 | ELECTRIC OUTBOARD MOTOR - An electric outboard motor main body including an electric motor and a propulsion section that applies the electric motor as motive power, and a power supply section supplying power to the electric motor and a control section controlling the electric motor that are disposed inside a hull separately from the electric outboard motor main body are provided, and the electric motor and the propulsion section are attached to enable a tilt-up operation via a tilt pin provided in a horizontal direction, and the electric motor is disposed higher than the tilt pin in a state before the tilt-up operation. | 10-06-2011 |
20120115376 | ENGINE CASE OF OUTBOARD MOTOR - An engine case houses engines in the inside of the case and is provided with a propulsion unit outside the case. A case main body housing the engines and assemblies of peripheral parts of the engines, and a case cover covering an opening at an upper portion of the case main body are included. Mufflers are installed on an exterior of a lower surface of the case, and on the lower surface of the case, housing portions housing the mufflers and exhaust hoses are formed. | 05-10-2012 |
20120286129 | STEERING DEVICE OF OUTBOARD MOTOR - An engine is housed in an engine case and a propulsion unit driven by the engine is provided outside the engine case. By a swivel bracket installed in a predetermined part of the engine case, the propulsion unit is pivotally supported around a steering shaft, and centers of a drive shaft driving the propulsion unit and of the steering shaft are matched. | 11-15-2012 |
20120304625 | EXHAUST DEVICE OF OUTBOARD MOTOR - A water jacket is attached to an exhaust manifold connected to an exhaust port to annularly cover an outer side of an exhaust channel in the exhaust manifold. An engine cooling coolant is made to flow as a cooling medium of the water jacket of the exhaust manifold. An exhaust pipe in a siphon shape is connected to the exhaust manifold, a water jacket is attached so as to annularly cover an outer side of a front half portion of the siphon shape, and seawater is directly supplied into the water jacket to flow therein. Consequently, an exhaust device of an outboard motor practically having a compact structure and excellent exhaust performance and accordingly realizing excellent engine performance is provided. | 12-06-2012 |
