Answer:
The answer to the question: What must you do to maintain steerage on a personal watercraft, also known as a PWC, is: apply throttle, because only when the throttle is engaged is the PWC manuverable. Otherwise, a rider on a PWC could lose completel control of the machine. In fact, according to most users manuals for PWCs explain, and insist, that if a rider on one of these boats faces an obstacle, or needs to avoid an object, they must never slow down, they must apply throttle, which means, they must speed up, in order to avoid accidents.
