Disclosed herein is a marine propulsion device including a shiftable, reversing transmission located in a propulsion unit and connecting a drive shaft to a propeller shaft and a shifting mechanism including an actuating member connected to the transmission. Movement of the actuating member to shift the transmission between a neutral condition and forward drive and reverse drive conditions is effected by a shifting system including a flexible dual cable conduit assembly connected between the actuating member and a shift lever mounted for reciprocal movement. The opposite ends of the two shift cables are linked together in a manner such that the movement of the shift lever in opposite directions causes alternate pulling of the shift cables to shift the transmission.
A marine propulsion device comprising a propulsion unit, a propeller shaft rotatably mounted in said propulsion unit and carrying a propeller, a drive shaft rotatably mounted in said propulsion unit, a reversing transmission connecting said drive shaft to said propeller shaft and shiftable between a neutral condition and a drive condition, shifting means including an actuating member mounted in said propulsion unit for reciprocal movement relative to a neutral position and connected to said reversing transmission for operating said reversing transmission in response to movement of said actuating member, a clutch shift lever mounted for reciprocal movement, and means connecting said shift lever to said actuating member for effecting movement of said actuating member in response to movement of said shift lever, said connecting means including first and second flexible shift cables each having a first end and a second end, means operably connecting said first ends of said shift cables to said shift lever and connecting said second ends of said shift cables to said actuating member such that, in response to movement of said shift lever in one direction, said first shift cable is pulled in a first direction for effecting movement of said actuating member in one direction relative to its neutral position and said second shift cable is moved in a second direction opposite to said first direction and such that, in response to movement of said shift lever in the other direction, said second shift cable is pulled in said first direction for effecting movement of said actuating member in the other direction relative to its neutral position and said first shift cable is moved in said second direction.
A marine propulsion device comprising a propulsion unit, a propeller shaft rotatably mounted in said propulsion unit and carrying a propeller, a drive shaft rotatably mounted in said propulsion unit, a reversing transmission connecting said drive shaft to said propeller shaft and shiftable between a neutral condition and forward and reverse drive conditions, shifting means including an actuating member mounted in said propulsion unit for movement transversely of said propeller shaft and connected to said reversing transmission for operating said reversing transmission in response to movement of said actuating member, a clutch shift lever mounted for rotational movement in opposite directions from a neutral position, and means connecting said shift lever to said actuating member for effecting movement of said actuating member in response to movement of said shift lever, said connecting means including first and second flexible shift cables, each having a first end and a second end, a part mounted for common rotation with said shift lever and having a surface extending arcuately with respect to the rotational axis of said shift lever, means connecting said first ends of said shift cables to said part such that, in response to rotational movement of said shift lever in one direction, a portion of said first shift cable is wound onto said surface and thereby pulled in a first direction while a portion of said second shift cable is unwound from said surface and thereby moved in a second direction opposite to said first direction and such that, in response to rotational movement of said shift lever in the opposite direction, a portion of said second shift cable is wound onto said surface and thereby pulled in said first direction while a portion of said first shift cable is unwound from said surface and thereby moved in said second direction, a rotatable drive member drivingly connected to said actuating member for effecting movement of said actuating member in response to rotational movement of said drive member, means connecting said second ends of said shift cables to said drive member such that, in response to pulling said first shift cable in said first direction, said drive member is rotated in one direction to effect movement of said actuating member in one direction transversely of the propeller shaft and such that, in response to pulling said second shift cable in said first direction, said drive member is rotated in the opposite direction to effect movement of said actuating member in the other direction transversely of the propeller shaft.
