- Jet drives use an engine to power a strong water pump. The pump sucks up water and then forces a jet of water out the back of the vessel to thrust the vessel forward. Directing this jet of water steers the vessel.
- PWC are the most common type of vessels that use a jet drive.
- Jet drives also may power larger vessels (jet boats) and are used commonly for vessels designed for shallow water conditions. Jet boats can have inboard or outboard jet drives.
