1. A method for notifying an operator of a marine vessel that a marine propulsion device propelling the marine vessel is not at an efficient trim angle, the method comprising:

  • determining a throttle valve position for a throttle valve on an engine of the marine propulsion device based on a helm input;

    moving the throttle valve to the throttle valve position;

    measuring a speed of the engine after moving the throttle valve to the throttle valve position;

    comparing the measured engine speed to an optimal engine speed corresponding to operation of the marine propulsion device at an optimal trim angle with the throttle valve at the same throttle valve position; and

    providing a notification that the marine propulsion device is not at an efficient trim angle if the measured engine speed is less than the optimal engine speed.
