Abstract
A method for setting an engine speed of an internal combustion engine in a marine propulsion device to an engine speed setpoint includes receiving an operator demand from an input device and learning an adapted maximum engine speed. An engine speed setpoint is calculated by scaling the adapted maximum engine speed relative to the operator demand. The method includes predicting a position of a throttle valve of the engine that is needed to achieve the engine speed setpoint, and determining a feed forward signal that will move the throttle valve to the predicted position. A marine propulsion system has an electronic control unit that learns the adapted maximum engine speed, calculates the engine speed setpoint by scaling the adapted maximum engine speed relative to the operator demand, predicts the position of the throttle valve, and determines the feed forward signal that will move the throttle valve to the predicted position.
