Abstract
A jet propulsion watercraft includes a watercraft body, a drive source in the watercraft body, a jet pump to suck and eject water with a drive force from the drive source to generate a propulsive force, a vibration sensor, and a controller. The vibration sensor is located in the jet pump to detect vibration of the jet pump. The controller is configured or programmed to determine whether or not a detection result from the vibration sensor meets a predetermined condition. The controller is configured or programmed to, when it is determined that the detection result from the vibration sensor meets the predetermined condition, inform a user of user-oriented information.
