Methods and systems for controlling trim position of a marine drive

Abstract:

A method of automatically controlling trim position of a marine drive with a control system on a marine vessel includes receiving a user-selected command associated with wake surfing and then controlling a trim actuator to automatically position the marine drive in a tucked position, tucked position is between a vertical trim position and a minimum running trim position. Once a vessel condition of the marine vessel reaches a first threshold vessel condition the trim actuator is controlled to trim up the marine drive to a predetermined target trim position to generate wave behind the marine vessel. The first threshold vessel condition is at least one of a threshold vessel speed, a threshold engine speed, a threshold engine load, and a threshold vessel pitch.
