Claim:
1. An outboard marine engine comprising: an internal combustion engine; a propulsor that is driven into rotation by the internal combustion engine so as to effect a thrust; a transmission that shifts amongst a forward gear wherein the thrust is a forward thrust, a reverse gear wherein the thrust is a reverse thrust, and a neutral gear wherein the thrust is a zero thrust; a shift rod that is rotatable about its own axis, wherein rotation of the shift rod about its own axis shifts the transmission amongst the forward gear, the reverse gear, and the neutral gear; an actuator operably connected to the internal combustion engine, wherein the actuator comprises a motor that rotates an output shaft; a first gearset connecting to the output shaft to a gear shaft such that rotation of the output shaft causes a gear shaft to rotate about its own axis, the first gearset comprising a first gear fixed to the output shaft that meshes with a second gear fixed to the gear shaft; and a second gearset connecting the gear shaft to the shift rod such that the rotation of the gear shaft about its own axis causes the rotation of the shift rod about its own axis, the second gearset comprising a third gear fixed to the gear shaft that meshes with a fourth gear fixed to the shift rod.
