A transmission for a marine propulsion system uses a cone clutch in such a way that, when in a forward gear position, torque is transmitted from an input shaft, or driving shaft, to an output shaft, or driven shaft, solely through the cone clutch. When in forward gear position, driving torque between the driving and driven shafts is not transmitted through any gear teeth. When in reverse gear position, torque is transmitted through an assembly of the bevel gears.

A transmission for a marine propulsion system, comprising:a first shaft supported for rotation about a first axis;a second shaft supported for rotation about a second axis, said first and second axes being generally parallel with each other; anda clutch which is alternately movable into first pos
1. A transmission for a marine propulsion system, comprising:a first shaft supported for rotation about a first axis;a second shaft supported for rotation about a second axis, said first and second axes being generally parallel with each other; anda clutch which is alternately movable into first position and second positions, said first position disconnecting said clutch from torque transmitting association with said first and second shafts and disconnecting said first and second shafts from torque transmitting association with each other, said second position connecting said clutch in torque transmitting association between said first and second shafts with torque being transferred from said first shaft to said second shaft solely through said clutch.2. The transmission of claim 1, further comprising:a first gear attached to said first shaft and rotatable about said first axis;a second gear which is rotatable about said second axis; andan intermediate gear disposed in gear tooth meshing association between said first and second gears.3. The transmission of claim 2, wherein:said first gear is a bevel gear;said intermediate gear is a bevel gear;said second gear is a bevel gear; andsaid clutch is alternately movable into a third position, said third position connecting said clutch in torque transmitting association between said second bevel gear and said second shaft, said first and second shafts being connected in torque transmitting association with each other through said first bevel gear, said intermediate bevel gear, said second bevel gear, and said clutch when said clutch is in said third position.4. The transmission of claim 1, wherein:said first and second axes are coaxial with each other.5. The transmission of claim 3, wherein:said intermediate bevel gear is rotatable about a third axis which in generally perpendicular to said first and second axes.6. The transmission of claim 1, wherein:said first shaft is connected in torque transmitting association with a crankshaft of an engine.7. The transmission of claim 1, wherein:said second shaft is connected in torque transmitting association with a propeller shaft.8. The transmission of claim 1, wherein:said clutch is connected in threaded engagement with said second shaft through a set of helical splines.9. The transmission of claim 1, wherein:said clutch is a cone clutch.10. A transmission for a marine propulsion system, comprising:a driving shaft supported for rotation about a first axis;a driven shaft supported for rotation about a second axis, said first and driven shafts being generally coaxial with each other; anda clutch which is alternately movable into first position and second positions, said first position disconnecting said clutch from torque transmitting association with said first and driven shafts and disconnecting said first and driven shafts from torque transmitting association with each other, said second position connecting said clutch in torque transmitting association between said first and driven shafts with torque being transferred from said driving shaft to said driven shaft solely through said clutch.11. The transmission of claim 10, further comprising:a first bevel gear attached to said driving shaft and rotatable about said first axis;a second bevel gear which is rotatable about said second axis; andan intermediate bevel gear disposed in gear tooth meshing association between said first and second bevel gears.12. The transmission of claim 11, wherein:said clutch is alternately movable into a third position, said third position connecting said clutch in torque transmitting association between said second bevel gear and said driven shaft, said first and driven shafts being connected in torque transmitting association with each other through said first bevel gear, said intermediate bevel gear, said second bevel gear, and said clutch when said clutch is in said third position.13. The transmission of claim 12, wherein:said first and second axes are generally parallel with each other.14. The transmission of claim 12, wherein:said first and second axes are coaxial with each other.15. The transmission of claim 10, wherein:said intermediate bevel gear is rotatable about a third axis which in generally perpendicular to said first and second axes.16. The transmission of claim 10, wherein:said driving shaft is connected in torque transmitting association with a crankshaft of an engine;said driven shaft is connected in torque transmitting association with a propeller shaft; andsaid clutch is connected in threaded engagement with said driven shaft through a set of helical splines, said clutch being a cone clutch.17. A transmission for a marine propulsion system, comprising:a driving shaft supported for rotation about a first axis;a driven shaft supported for rotation about a second axis, said first and driven shafts being generally coaxial with each other;a cone clutch which is alternately movable into first position and second positions, said first position disconnecting said cone clutch from torque transmitting association with said first and driven shafts and disconnecting said first and driven shafts from torque transmitting association with each other, said second position connecting said cone clutch in torque transmitting association between said first and driven shafts with torque being transferred from said driving shaft to said driven shaft solely through said cone clutch;a first bevel gear attached to said driving shaft and rotatable about said first axis;a second bevel gear which is rotatable about said second axis; andan intermediate bevel gear disposed in gear tooth meshing association between said first and second bevel gears.18. The transmission of claim 17, wherein:said cone clutch is alternately movable into a third position, said third position connecting said cone clutch in torque transmitting association between said second bevel gear and said driven shaft, said first and driven shafts being connected in torque transmitting association with each other through said first bevel gear, said intermediate bevel gear, said second bevel gear, and said cone clutch when said cone clutch is in said third position, said first and second axes being generally coaxial with each other, said driving shaft being connected in torque transmitting association with a crankshaft of an engine, said driven shaft being connected in torque transmitting association with a propeller shaft, said cone clutch being connected in threaded engagement with said driven shaft through a set of helical splines, said cone clutch being a cone clutch.19. The transmission of claim 18, wherein:said intermediate bevel gear is rotatable about a third axis which in generally perpendicular to said first and second axes.
