A system for controlling a tilt-trim position of a propulsion device on a marine vessel includes a user input device generating a command to rotate the propulsion device to a desired tilt-trim position, a position sensor sensing a current tilt-trim position of the propulsion device, a control module receiving the user command and the current tilt-trim position, and a tilt-trim actuator rotating the propulsion device. In response to determining that the propulsion device's engine is not running, the control module rotates the propulsion device until the desired tilt-trim position is achieved, and starts the engine in response to determining that the current tilt-trim position does not exceed a threshold. In response to determining that the engine is running, the control module determines whether a vessel and/or engine speed condition is met, and if so, rotates the propulsion device about the tilt-trim axis until the desired tilt-trim position is achieved.
