A finger throttle is a type of throttle control that is commonly used on personal watercraft (PWC) such as jet skis, Sea-Doos, and WaveRunners. The finger throttle is typically mounted on the handlebars of the PWC and is operated by the rider using their fingers.

The finger throttle consists of a small lever or button that is mounted on the handlebars, and is connected to the throttle body of the PWC's engine via a throttle cable. As the rider moves the lever or presses the button, the throttle cable transmits the movement to the throttle body, which adjusts the flow of fuel to the engine. This allows the rider to control the speed of the PWC.

Finger throttles are a convenient and easy-to-use method of controlling the speed of a PWC, and are particularly popular on high-performance models. They are typically durable and reliable, and are designed to withstand the high speeds and forces that are common in PWC operation. Finger throttles should be regularly inspected and maintained to ensure they are functioning properly.
