A Scarab jet pump is a device that is used to propel a Scarab boat through the water. It consists of an impeller, a housing, and a steering nozzle. The Scarab impeller is a rotating blade that is driven by the Scarab boat's engine and draws water into the housing. The water is then forced out through the steering nozzle, which is used to steer the boat.

The Scarab jet pump is located at the back of the boat and is responsible for providing the thrust that propels the Scarab boat through the water. It is a key component of the Scarab boat's propulsion system and is essential for the Scarab boat's performance and handling.

Scarab jet pumps are designed to be durable and reliable, and they are typically made from high-quality materials such as stainless steel and aluminum. They are also designed to be easy to maintain, with components that can be easily accessed and replaced if necessary.

To ensure the best performance and longevity of the Scarab jet pump, it is important to follow the manufacturer's recommendations for maintenance and to use the boat in accordance with the manufacturer's guidelines. This may include regularly cleaning and lubricating the Scarab jet pump and avoiding excessively rough or shallow water.
