ABSTRACT:
A thrust control apparatus for a jet propulsion watercraft is provided. The thrust control apparatus includes a throttle sensor for detecting a fully-closed operation of a throttle of the engine, a steering sensor for detecting steering of a steering device more than a predetermined amount from a neutral position of the steering device and a direction of the steering; a control device configured to control the engine such that the water jet pump generates a different thrust for rightward and leftward steering, in accordance with the steering direction detected by the steering sensor, when the throttle sensor detects the fully-closed operation of the throttle and the steering sensor detects steering of more than the predetermined amount.
