摘要：
A marine propulsion system includes a power source, a propeller, a shift mechanism, a control lever, a rotational speed sensor, and a control device. The shift mechanism is switchable among three shift positions including forward, neutral, and reverse. The control lever is operable by the marine vessel operator to switch the shift position of the shift mechanism. The rotational speed sensor detects the rotational speed of the propeller. The control device controls at least one of the power source and the shift mechanism so as to reduce the rotational speed of the propeller if the rotational speed sensor detects a rotational speed of the propeller when the control lever is in a position corresponding to the neutral shift position. As a result, the propeller is prevented from rotating when a control lever is in a neutral position.
