1. A gearcase for a marine propulsion system, comprising:
an input shaft rotatable about a central axis of rotation;
an output shaft coaxially arranged with the input shaft such that the input shaft extends through the output shaft;
a clutch assembly operable between a first clutch position and a second clutch position, wherein, when the clutch assembly is in the first clutch position, the input shaft is coupled to the output shaft for rotating the output shaft in a first rotational direction; and
a gear assembly operably connecting the input shaft to the output shaft, wherein when the clutch assembly is in the second clutch position the gear assembly is arranged to rotate the output shaft in an opposite second rotational direction.
