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.
