Abstract:
1. A marine propulsion system, comprising: an input shaft which is connectable in torque transmitting relation with an engine; a first intermediate shaft which is connected in torque transmitting relation with said input shaft and rotatable about a first axis of rotation; a second intermediate shaft which is connected in torque transmitting relation with said first intermediate shaft and rotatable about a second axis of rotation; and a drive shaft which is connectable in torque transmitting relation with said second intermediate shaft; a first bevel gear connected in torque transmitting relation with said second intermediate shaft to rotate in a first direction; a second bevel gear connected in torque transmitting relation with said second intermediate shaft to rotate in a second direction; and a clutch which is movable between a first position to cause said drive shaft to rotate in said first direction and a second position to cause said drive shaft to rotate in said second direction; a drive shaft housing, said drive shaft and said first and second bevel gears being supported for rotation about a drive shaft axis of rotation by said drive shaft housing; an intermediate housing, said first and second intermediate shafts being supported for rotation about said first and second axes of rotation by said intermediate housing; a first hydraulic cylinder connected between said drive shaft housing and said intermediate housing; and a propeller shaft connected in torque transmitting relation with said drive shaft.
