。[Scope of Claim for Utility Model Registration] A computing device that calculates the deviation between the commanded rotation speed and the actual rotation speed, a PID controller that performs proportional, integral, and differential operations on the deviation and outputs it as an actuator position command, and a command rotation speed, etc. A marine main engine control device comprising: a limiter that sets an upper limit of an actuator position command for the actuator position command and passes the actuator position command; and an actuator that operates based on the actuator position command to control the fuel rack position. A first setting device that outputs an actuator position command dedicated to the normal start of the main engine, a second setting device that outputs an actuator position command dedicated to the rapid reverse start of the main engine, and comparing the above actual rotation speed with the command rotation speed. The comparator outputs a first signal when the actual rotation speed is lower than the command rotation speed, and outputs a second signal when the actual rotation speed exceeds the command rotation speed. At startup,
Based on the first signal, transmission of the actuator position command from the limiter to the actuator is cut off, and the first signal is
A switch for transmitting the actuator position command from the setting device or the second setting device to the actuator, and returning to transmitting only the actuator position command from the limiter to the actuator based on the second signal. A marine main engine control device characterized by:
