Ship propulsion machine control system

A ship propulsion machine control system for controlling a propulsive force for a boat generated by a ship propulsion machine, the ship propulsion machine control system comprising:

• an operating device including:
• a main operation portion configured to perform an operation to change the propulsive force;
• and
• a main operation signal output section configured to output a main operation signal according to an operation of the main operation portion;
• a gauge including:
• a display unit configured to display information related to the ship propulsion machine;
• a secondary operation unit configured to perform an operation to change the propulsive force;
• and
• a secondary operation signal output section configured to output a secondary operation signal according to an operation of the secondary operation unit;
• an abnormality detection section configured to detect an abnormality in the operating device;
• and
• a control device configured to:
• change the propulsive force based on the main operation signal, in a case where no abnormality in the operating device is detected by the abnormality detection section;
• and
• change the propulsive force based on the secondary operation signal, in a case where an abnormality in the operating device is detected by the abnormality detection section.
