Abstract

A marine vessel propulsion control system includes a simulated ship speed calculator which calculates a simulated ship speed by multiplying an engine rotational speed when the ship travels forward in a propeller co-rotating state and the power transmission mechanism continues the forward connection state by a scale conversion coefficient corresponding to a ship length, and which decreases the simulated ship speed based together with elapse of time. A shift controller, in a case where the simulated ship speed is not equal to or less than a predetermined simulated ship speed threshold when the operation part is changed from the forward position to the neutral position and is subsequently changed to the reverse position, switch the state of the power transmission mechanism from the disconnection state to the reverse connection state after waiting for the simulated ship speed to become equal to or less than the simulated ship speed threshold.
