System and method for trimming a trimmable marine device with respect to a marine vessel

A system for controlling a trim position of a trimmable marine device with respect to a marine vessel to which the trimmable marine device is coupled, the system comprising:

• a controller that determines a target trim position of the marine device based on a condition of the marine vessel;
• a trim position sensor that senses an actual trim position of the marine device and sends actual trim position information to the controller;
• and
• a trim actuator coupled to the marine device and configured to rotate the marine device about a horizontal trim axis in response to commands from the controller;
• wherein the controller determines at least a magnitude of an acceleration rate of the marine vessel;
• wherein, in response to determining that the magnitude of the acceleration rate exceeds a given rate threshold, the controller commands the trim actuator to rotate the marine device until the trim position sensor indicates that the actual trim position equals the target trim position;
• and
• wherein, in response to determining that the magnitude of the acceleration rate does not exceed the given rate threshold, the controller commands the trim actuator to rotate the marine device until the trim position sensor indicates that the actual trim position equals a setpoint trim position that is different from the target trim position.
