What is the primary propulsion source for personal watercraft (PWC)?

The primary propulsion source for personal watercraft (PWC) is the inboard jet drive. A PWC uses a jet drive system, which draws water in through a intake, then compresses it and expels it through a nozzle at the rear, creating thrust. This design allows for quick acceleration and maneuverability, making PWCs popular for recreational use. The jet drive also provides safety benefits, as there are no exposed propellers, reducing the risk of injury in the water.

The other options do not accurately describe the propulsion systems used in PWCs: outboard motors are typically found on larger boats, rowing involves manual propulsion without a mechanical engine, and sail propulsion utilizes wind, which is not applicable to the operation of a PWC.
