PROBLEM TO BE SOLVED: To provide a new or improved outboard motor marine propulsion system which allows for the output of substantially greater power levels than conventional outboard motor marine propulsion systems.SOLUTION: An outboard motor 104 includes a horizontal-crankshaft engine in an upper portion of the outboard motor, and the horizontal-crankshaft engine is positioned substantially above a trimming axis 112 of the outboard motor. In at least another embodiment, first, second and third transmission devices are employed to transmit rotational power from the engine to one or more propellers 130 at a lower portion of the outboard motor. In at least a further embodiment, the outboard motor includes a rigid interior assembly formed by the engine, the multiple transmission devices, and a further structural component. In further embodiments, the outboard motor includes numerous cooling, exhaust, and/or oil system components as well as other transmission structures.SELECTED DRAWING: Figure 1 |
