    摘要： A marine propulsion system (100) includes a controller (50) configured or programmed to perform an electric drive control to cause an electric motor (32) to drive an auxiliary thruster (31) having a minimum output smaller than a minimum output of a main thruster (21) in an auxiliary propulsion device (30) without performing an engine drive control to cause an engine (22) to drive the main thruster (21) in a main propulsion device (20) when adjusting a thrust (P) of a marine vessel (110) to less than a troll thrust (P trl ).

    摘要： A control system for a marine propulsion device capable of driving a propeller (18) by either an engine (23) or a motor (25) is provided. The control system includes a first memory (40a) configured to hold first information for identifying whether the control system has shut down normally or abnormally even during a reset period of the control system, a second memory (22a, 26a) configured to hold second information indicating control states of the engine and the motor even during the reset period of the control system, and a controller (40). The controlled is configured or programmed to start controlling the engine and the motor, based on the second information held in the second memory, in a case where the first information held in the first memory indicates an abnormal shutdown of the control system at a startup of the control system.

    摘要： A control device of a battery of a marine vessel that ensures electric power for starting an engine with priority is provided. A first value indicating either a voltage or a power storage amount of a main battery that supplies electric power for starting the engine is acquired. In a case where the first value that has been acquired is smaller than a first threshold value, at least one of a prohibition of a transition to a motor drive mode (S104) in which a propeller is driven by using at least a motor regardless of an operation mode that is designated and a prohibition of charging of a load battery is performed, and the engine is caused to rotate to charge the main battery.
