A Yamaha WaveRunner scoop grate, also known as an intake grate, is a component that is used to direct water into the intake system of a Yamaha WaveRunner personal watercraft (PWC). The scoop grate is located at the front of the WaveRunner, and is designed to allow water to flow into the intake system while preventing debris from entering the engine.

The scoop grate consists of a series of channels or slots that are arranged in a specific pattern. As the WaveRunner moves through the water, the scoop grate captures water and directs it into the intake system, where it is used to cool and lubricate the engine. The channels or slots in the scoop grate are typically designed to minimize drag and maximize performance, and may be adjustable to allow for different riding conditions.

Yamaha WaveRunner scoop grates are an important component of the WaveRunner's cooling and lubrication system, and are critical to the performance and reliability of the watercraft. They should be regularly inspected and maintained to ensure they are functioning properly.
