A PWC uses a moveable nozzle connected to a jet pump, rather than a propeller, to power the vessel. This distinction affects the operating and handling characteristics of the vessel. The most notable distinction is “off-throttle steering,” a trade term for the situation that exists when an operator releases the throttle and then attempts to execute a turn.
The term is an oxymoron because there is little or no steering capability when the throttle is off. Turning the PWC handlebars changes the angle of water exiting the jet pump, but without power to the jet pump, there is little or no directional thrust. As stated in the owner’s safety manual of one PWC manufacturer, “Remember, releasing the throttle completely eliminates the ability to steer the watercraft.” This operating characteristic is likely to be counterintuitive to novice operators, particularly in situations of potential collision.
