Abstract
Systems and methods are for controlling shift in a marine propulsion device. A shift sensor outputs a position signal representing a current position of a shift linkage. A control circuit is programmed to identify an impending shift change when the position signal reaches a first threshold and an actual shift change when the position signal reaches a second threshold. The control circuit is programmed to enact a shift interrupt control strategy that facilitates the actual shift change when the position signal reaches the first threshold, and to actively modify the first threshold as a change in operation of the marine propulsion device occurs.
