Which action may cause the loss of steering ability in a PWC?

Letting off the throttle control can indeed lead to a loss of steering ability in a personal watercraft (PWC). PWCs operate with a steering system that relies on thrust from the water jet to maneuver. When the throttle is engaged, the engine produces thrust, allowing the operator to steer effectively. By releasing the throttle, the thrust is reduced or eliminated, which can result in the inability to steer or control the direction of the PWC properly. This is particularly critical when maneuvering, as without adequate thrust, the PWC may continue to travel in a straight line, making it difficult to respond to obstacles or changes in the environment. Therefore, understanding the importance of maintaining throttle control is essential for safe operation and navigation of a PWC.
