What is the most important thing to let someone know if you allow them to use your PWC?

The most important thing to communicate if you allow someone to use your personal watercraft (PWC) is that it cannot be steered when it is turned off or idling. Understanding this is crucial for safe operation. When a PWC is not running, the operator loses control over its direction and ability to maneuver, which can lead to dangerous situations, especially in busy or crowded waters. Having a clear understanding of this limitation helps ensure that the operator is prepared and can navigate safely.

The other options may describe attributes of the PWC, but they do not emphasize the critical safety aspect that pertains to steering and control. Fuel capacity, passenger limits, and speed are important considerations, but without the ability to steer effectively, the likelihood of accidents increases significantly. Thus, being aware of the steering limitation is the most critical information to share.
