1. A jet propulsion boat comprising:
- a boat body;
a jet propelling apparatus configured to propel the boat body;
an engine configured to drive the jet propelling apparatus;
a speed determination section configured or programmed to determine whether or not the boat body is in a first speed traveling state, the first speed traveling state being when a number of engine revolutions or a boat speed is not smaller than a threshold value;
a turning state determination section configured or programmed to determine whether or not the boat body is in a turning state; and
a controller configured or programmed to control the engine based on results of the determinations made by the speed determination section and the turning state determination section;
whereinthe controller is configured or programmed to decrease a number of revolutions of the engine if the speed determination section determines that the boat body is in the first speed traveling state and the turning state determination section determines that the boat body is in the turning state.

Abstract
A jet propulsion boat includes a boat body, a jet propelling apparatus configured to propel the boat body, an engine configured to drive the jet propelling apparatus, and an ECU. The ECU is configured or programmed to determine that a deceleration operation is performed when an amount of operation of a first accelerator operation section is greater than an amount of operation of a second accelerator operation section. The ECU sets an upper limit value for the number of revolutions of the engine to a first predetermined value if the boat body is in a first speed traveling state and the boat body is in a turning state.
