A method for controlling a speed of a propeller of a marine propulsion device during launch of a marine vessel comprises receiving a command to initiate an enhanced launch feature of the marine vessel. The method includes increasing a speed of an engine of the marine propulsion device in response to the enhanced launch feature command. While the engine speed increases, the method includes commanding a first amount of engagement of a forward gear controlling torque transfer from an output shaft of the engine to an input shaft of the propeller. After the engine speed reaches a predetermined threshold, the method includes commanding a second, greater amount of engagement of the forward gear controlling torque transfer from the engine output shaft to the propeller input shaft.
