Ship maneuvering device

A ship maneuvering device comprising:

• an engine;
• an outdrive device having a propeller rotated by power of the engine;
• a clutch engaging and disengaging power transmission from the engine to the propeller;
• an operation means actuating the outdrive device;
• and
• a control device connected to the engine, the clutch and the operation means,
• characterized in that
• the control device has a very low speed sailing mode,
• the control device is connected to a determination means determining whether the very low speed sailing mode is executed or not, and
• in a case in which execution of the very low speed sailing mode is determined, when an operation amount of the operation means is not more than a baseline operation amount, the control device makes a rotation speed of the engine be a low idling rotation speed and changes a duty ratio, which is a ratio of a time in which the clutch at a predetermined cycle has been turned on corresponding to the operation amount of the operation means, within a range not more than 100%.
