A reverse cable is a flexible, wire-like component that is used to transmit the rider's input to engage the reverse gear on a boat or personal watercraft (PWC). Reverse cables are typically used in boats or PWCs that have mechanical reverse systems, in which the reverse gear is activated by a lever or other manual control.

The reverse cable is typically connected to the reverse lever or control at one end and to the reverse mechanism at the other end. As the rider activates the reverse lever or control, the reverse cable transmits the movement to the reverse mechanism, which engages the reverse gear. This allows the boat or PWC to move backwards under the power of the engine.

Reverse cables are typically made from a strong, flexible material such as steel or Kevlar, and are designed to withstand the high speeds and forces that are common in boat and PWC operation. They are an important component of the reverse system, and are critical to the smooth and safe operation of the vehicle. Reverse cables should be regularly inspected and maintained to ensure they are functioning properly.
