Jet-propulsion watercraft
First Claim
1. A jet-propulsion watercraft, comprising:
- a water jet pump including an outlet port and a steering nozzle, said water jet pump pressurizing and accelerating sucked water and ejecting the water from the outlet port to propel the watercraft as a reaction of the ejecting water;
a steering operation means operating in association with the steering nozzle of the water jet pump;
a steering position sensor for detecting a steering operation of the steering operation means;
a steering means adapted to be subjected to a steering assist mode control, when a signal indicating that the steering position sensor has detected the steering operation is received from the steering position sensor; and
a control device that gives a signal to the steering position sensor and receives a signal indicating that the steering operation means is or is not steered from the steering position sensor, wherein the signal from the steering position sensor is set equal in level to the signal being given from the control device to the steering position sensor when the steering operation means is not steered.

Abstract
A jet-propulsion watercraft, comprises a steering position sensor for detecting a steering operation of a steering operation means. A steering means adapted to be subjected to a steering assist mode control, when a signal indicating that the steering position sensor has detected the steering operation is received from the steering position sensor. A control device that gives a signal to the steering position sensor and receives a signal indicating that the steering operation means is or is not steered from the steering position sensor, and the signal from the steering position sensor is set equal in level to the signal given from the control device to the steering position sensor when the steering operation means is not steered.
