Abstract

A method for controlling a trim position of a marine propulsion device includes receiving operator demands corresponding to propulsion system operating speeds and determining a rate of change of demand versus time between an initial and a subsequent operator demand. When the rate of change of demand exceeds a predetermined rate, the control module uses successively measured operating speeds of the propulsion system and an offset trim profile to determine setpoint trim positions for the propulsion device. As the propulsion system's measured operating speed increases from an initial to a subsequent operating speed, the control module controls a trim actuator to rotate the propulsion device to the setpoint trim positions. An operating speed at which the propulsion device begins trimming up is less according to the offset trim profile than according to a base trim profile, which is utilized when the rate of change does not exceed the predetermined rate.
