Abstract

A system for controlling trim position of a marine propulsion device on a marine vessel includes a trim actuator having a first end configured to couple to the marine propulsion device and a second end configured to couple to the marine vessel. A controller controls position of the trim actuator between an extended position wherein the propulsion device is trimmed up with respect to the vessel and a retracted position wherein the propulsion device is trimmed down with respect to the vessel. A shock relief mechanism overrides position control by the controller and allows extension of the trim actuator upon the occurrence of an overpressure event. An arresting mechanism, when activated, prevents extension of the trim actuator beyond a certain limit. The controller selectively activates the arresting mechanism in response to a determination that the propulsion device is being commanded in reverse. Methods for controlling trim position are also included.
