Abstract
A system for controlling a rotational speed of a marine internal combustion engine has a first operator input device for controlling a speed of the engine in a trolling mode, in which the engine operates at a first operator-selected engine speed so as to propel a marine vessel at a first non-zero speed. A second operator input device controls the engine speed in a non-trolling mode, in which the engine operates at a second operator-selected engine speed so as to propel the marine vessel at a second non-zero speed. A controller is in signal communication with the first operator input device, the second operator input device, and the engine. In response to an operator request to transition from the trolling mode to the non-trolling mode, the controller determines whether to allow the transition based on the second operator-selected engine speed and a current engine speed.
