In a small boat equipped with a display panel (liquid crystal device) displaying operation information and a change-over switch (set switch) capable of switching from a normal operation in which output of an engine is not limited to a limited operation in which the output of the engine is limited low, the display panel has a display lamp (limit mode display mark) for lighting when switched to the limited operation. Since there is provided a display lamp for lighting when switched to the limited operation for a small boat capable of switching from a normal operation in which output of an engine is not limited to a limited operation in which the output of the engine is limited low, the convenience can be afforded to the operator.
