Patent ID: 10933963

Abstract:
A method for controlling a trim-tilt angle of a propulsion unit of a marine outboard motor. The method includes: receiving a request to increase the trim-tilt angle of the propulsion unit; determining a motor operation parameter; determining the trim-tilt angle of the propulsion unit; prior to increasing the trim-tilt angle in response to the request, determining if the propulsion unit is in a trim limit condition; increasing the trim-tilt angle of the propulsion unit in response to the request when the propulsion unit is determined not to be in the trim limit condition; and one of maintaining the trim-tilt angle of the propulsion unit and stopping increase of the trim-tilt angle of the propulsion unit when the propulsion unit is determined to be in the trim limit condition. A method for controlling the trim-tilt angle in view of an over-trim condition of the propulsion unit is also disclosed.
