Claims
- 1. A marine propulsion system adapted to be attached at the rear of a watercraft hull for propelling the watercraft, said propulsion system comprising a powering internal combustion engine, a drive shaft housing and lower unit journaling a propeller shaft that is driven by said engine and which extends generally horizontally rearwardly from the watercraft hull, a propulsion device driven by the rear end of the propeller shaft, means for supporting said propulsion system for steering and tilting movement about respective vertically and horizontally extending transverse axes which are disposed below and to the rear of the portion of the hull to which the marine propulsion system is attached, and a tiller affixed to the upper end of said drive shaft housing and lower unit and extending forwardly into the watercraft for operator control of the steering and trim of said propulsion system, the distance between said trim axis and the propulsion device being greater than the distance between the forward end of the tiller and said trim axis.
- 2. A marine propulsion system as set forth in claim 1, wherein the tiller and the propeller shaft are parallel to each other.
- 3. A marine propulsion system as set forth in claim 2, wherein the axis about which the propeller shaft rotates intersects the trim axis.
- 4. A marine propulsion system as set forth in claim 3, wherein the steering axis and the tilt axis do not intersect each other.
- 5. A marine propulsion system as set forth in claim 4, wherein the steering axis and the tilt axis are spaced longitudinally from each other.
- 6. A marine propulsion system as set forth in claim 5, wherein the tilt axis is disposed to the rear of the steering axis.
- 7. A marine propulsion system as set forth in claim 5, wherein attachment of the propulsion system to the hull is provided by a generally L-shaped bracket having a horizontal leg adapted to be affixed to the hull and a vertical leg extending vertically downwardly toward the water level, a bracket carried by the lower end of said vertical leg, said vertical leg supporting rearwardly thereof a vertically extending steering pin which defines said vertically extending steering axis, a yoke pivotally supported at its forward end by said steering pin and extending rearwardly therefrom to embrace a lower portion of the drive shaft housing and lower unit and to provide the pivotal connection thereto that defines the transverse tilt axis.
- 8. A marine propulsion system adapted to be attached at the rear of a watercraft hull for propelling the watercraft, said propulsion system comprising a powering internal combustion engine, a drive shaft housing and lower unit journaling a propeller shaft that is driven by said engine and which extends generally horizontally rearwardly from the watercraft hull, a propulsion device driven by the rear end of the propeller shaft, means for supporting said propulsion system for steering and tilting movement about respective vertically and horizontally extending transverse axes which are disposed below and to the rear of the portion of the hull to which the marine propulsion system is attached, a tiller affixed to the upper end of said drive shaft housing and lower unit and extending forwardly into the watercraft for operator control of the steering and trim of said propulsion system, a generally L-shaped bracket having a horizontal leg adapted to be affixed to the hull and a vertical leg extending vertically downwardly toward the water level, a bracket carried by the lower end of said vertical leg, said vertical leg supporting rearwardly thereof a vertically extending steering pin which defines said vertically extending steering axis, and a yoke pivotally supported at its forward end by said steering pin and extending rearwardly therefrom to embrace a lower portion of said drive shaft housing and lower unit and to provide the pivotal connection thereto that defines said transverse trim axis.
