Answer:
The answer to the question: What is the most important thing to remember about steering a pwc, would be, that you must always maintain power, meaning, you must never turn off the engine, or put it in iddle, while steering. If this happens, all manuverability will be lost and regardless of what you do, the machine will continue on its course.
Step-by-step explanation:
In all manuals regarding the correct management of pwc´s and any boat that is moved through jets, the one thing that is always set at the top of the list of things to know, is that power must be maintained, that the engine of the boat must never be turned off suddenly, as a means to seek either manuverability or to stop the boat´s motion. What is more, they insist that if an operator does something like that, he will not only lose control of the boat, but the machine will continue on the course that had been set before losing power on the engine.
