An apparatus is for a changing gear in a marine propulsion system. A cam rotates about a first axis with a shift shaft. The cam has a body and an arm that radially extends from the body with respect to the first axis. A cam follower moves parallel to a second axis that is perpendicular to the first axis to cause movement of a clutch, thereby enacting a gear change. The cam follower defines a pocket that is elongated with respect to the second axis and a recess that extends from the pocket along a third axis that is perpendicular to the first and second axes. The cam is disposed in the pocket and the arm extends into the recess. During a constant rotation of the shift shaft in a first direction about the first axis, the cam follower moves with respect to the second axis to enact the gear change and also dwells with respect to the second axis.
