A Sea Doo pump is a mechanical device that is used to propel a SeaDoo, which is a brand of personal watercraft. The pump consists of a housing that encloses a series of impellers and diffusers, which are designed to create a high-velocity jet of water that propels the watercraft through the water.

The pump is located at the rear of the Sea-Doo and is powered by the engine through a driveshaft. As the engine runs, it rotates the driveshaft, which in turn rotates the impellers inside the pump housing. The impellers draw in water through an intake at the front of the pump and then accelerate it through the diffusers, creating a jet of water that propels the SeaDoo forward.

The pump is a critical component of a Sea-Doo, as it is responsible for providing the thrust needed to move the watercraft through the water. It must be able to withstand the high speeds and stresses that are encountered during operation, and it must be carefully designed and balanced to ensure efficient and smooth operation.

Proper maintenance and care of the pump is important to ensure that it performs at its best and has a long service life. This includes regularly inspecting the pump for wear and damage, and replacing it as needed. It is also important to ensure that the pump is properly lubricated and aligned to minimize wear and ensure smooth operation.
