First, you are replying to something that was posted over a decade ago.

Second, you misunderstood Leon's post. He did not say that the motor
needed water to run it, he said "most come with instructions to not run
the motor unless the water is running."

Similar to the motor in a car, it doesn't need water to run, but it sure
does like something to keep it cool, thus *keeping* it running.
