Thrust control device for jet propulsion watercraft
First Claim
1. A thrust control apparatus for a jet propulsion watercraft including a water jet pump driven by an engine, wherein the watercraft travels by a thrust generated by the water jet pump, the thrust control apparatus comprising:
- 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.
