  2. Marine propulsion - Wikipedia

    en.wikipedia.org/wiki/Marine_propulsion

    A pump-jet, hydrojet, water jet, or jet drive uses a ducted propeller (axial-flow pump), centrifugal pump, or mixed flow pump to create a jet of water for propulsion. These incorporate an intake for source water and a nozzle to direct its flow out, generating momentum, and in most cases, employing thrust vectoring to steer the craft.

  3. Pump-jet - Wikipedia

    en.wikipedia.org/wiki/Pump-jet

    A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller ( axial-flow pump ), a centrifugal pump , or a mixed flow pump which is a combination of both centrifugal and axial designs.

  4. Magnetohydrodynamic drive - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_drive

    A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics. The fluid is directed to the rear and as a reaction, the vehicle accelerates forward. [1] [2]

  5. Internal drive propulsion - Wikipedia

    en.wikipedia.org/wiki/Internal_drive_propulsion

    Internal drive propulsion or water-jet propulsion is a form of marine propulsion used in recreational boating.Like other forms of motorized boating, internal drive propulsion employs a motor that turns a propeller to move the boat forward.

  7. Jetboat - Wikipedia

    en.wikipedia.org/wiki/Jetboat

    A jetboat is a boat propelled by a jet of water ejected from the back of the craft. Unlike a powerboat or motorboat that uses an external propeller in the water below or behind the boat, a jetboat draws the water from under the boat through an intake and into a pump-jet inside the boat, before expelling it through a nozzle at the stern.

  8. Z-drive - Wikipedia

    en.wikipedia.org/wiki/Z-drive

    A Z-drive is a type of marine propulsion unit. Specifically, it is an azimuth thruster . The pod can rotate 360 degrees allowing for rapid changes in thrust direction and thus vessel direction.

  9. Sterndrive - Wikipedia

    en.wikipedia.org/wiki/Sterndrive

    The outdrive unit of a boat with sterndrive. A sterndrive or inboard/outboard drive (I/O) is a form of marine propulsion which combines inboard power with outboard drive. The engine sits just forward of the transom while the drive unit (outdrive or drive leg) lies outside the hull.
