Abstract
A method of controlling trim position of a propulsion device includes receiving a current engine speed and a current trim position of the propulsion device, and then detecting at least a threshold increase in engine speed of the propulsion device or at least a threshold drop in engine load on the propulsion device. A reduced trim position is then determined based on the current trim position, and a trim actuator is operated to move the propulsion device to the reduced trim position.

A method of controlling trim position of a propulsion device on a marine vessel, the method comprising:
- receiving a current trim position of the propulsion device;
- detecting at least one of a threshold increase in engine speed of the propulsion device and a threshold drop in engine load on the propulsion device indicating reduced resistance on a propeller of the propulsion device;
- upon detecting the threshold increase in engine speed or the threshold drop in engine load, determining a reduced trim position based on the current trim position;
- and
- operating a trim actuator to move the propulsion device to the reduced trim position.
A system for controlling trim position of a propulsion device on a marine vessel, the system comprising:
- a trim actuator configured to adjust a trim position of the propulsion device;
- a controller configured to:
- receive a current trim position of the trim actuator;
- detect at least one of a threshold increase in engine speed of the propulsion device and a threshold drop in engine load on the propulsion device indicating reduced resistance on a propeller of the propulsion device;
- upon detecting the threshold increase in engine speed or the threshold drop in engine load, determine a reduced trim position based on the current trim position;
- and
- operate the trim actuator to move the propulsion device to the reduced trim position.
