Outboard Marine Drive

Abstract

An outboard marine drive with an engine is described. The marine drive may include a drive housing with an upper drive housing and lower drive housing. The drive housing may be configured to be attached to a transom of a marine craft. An upper drive assembly may be located in the upper drive housing. A lower gear drive assembly may be located in the lower drive housing. A cone clutch may be located in the lower drive housing to engage the upper drive assembly with the lower gear drive assembly.

1 . An outboard marine drive with an engine, comprising:
 a drive housing having an upper drive housing and lower drive housing, the drive housing configured to be attached to a transom of a marine craft;   an upper drive assembly located in the upper drive housing;   a lower gear drive assembly located in the lower drive housing; and   a cone clutch located in the lower drive housing to engage the upper drive assembly with the lower gear drive assembly.   
     
     
         2 . The outboard marine motor as in  claim 1 , further comprising a propeller shaft coupled to the lower gear drive assembly. 
     
     
         3 . The outboard marine motor as in  claim 1 , further comprising a propeller attached to the propeller shaft. 
     
     
         4 . The outboard marine motor as in  claim 1 , further comprising a transmission with multiple gear ratios. 
     
     
         5 . The outboard marine motor as in  claim 4 , wherein the transmission receives power from the engine through the upper drive assembly and transmits power to the lower gear drive assembly through the cone clutch. 
     
     
         6 . The outboard marine motor as in  claim 4 , wherein the transmission includes a gear ratio selection for forward or reverse motion of the marine craft. 
     
     
         7 . The outboard marine motor as in  claim 4 , further comprising multiple forward gears in the transmission. 
     
     
         8 . The outboard marine motor as in  claim 4 , further comprising multiple reverse gears in the transmission. 
     
     
         9 . The outboard marine motor as in  claim 1 , wherein the cone clutch provides forward, neutral and reverse motion of the marine craft. 
     
     
         10 . The outboard marine motor as in  claim 1 , further comprising a steering handle attached to the drive housing to steer the outboard marine motor. 
     
     
         11 . The outboard marine motor as in  claim 1 , further comprising a throttle control to control the speed of the outboard marine motor. 
     
     
         12 . The outboard marine motor as in  claim 1 , further comprising a rudder fin on the lower drive housing of the outboard marine motor. 
     
     
         13 . The outboard marine motor as in  claim 1 , further comprising a cavitation plate fin on the lower drive housing of the outboard marine motor. 
     
     
         14 . The outboard marine motor as in  claim 1 , wherein the lower drive housing partially extends below the bottom of the marine craft. 
     
     
         15 . The outboard marine motor as in  claim 1 , further comprising a shifter to control forward, neutral, or reverse. 
     
     
         16 . The outboard marine motor as in  claim 15 , wherein the shifter is an electric or magnetic shifter with a servomechanism.
