Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller.

Super Soaker later made many motorized water guns. In 2011, they released the Thunderstorm, which used an electric pump to push water directly out the nozzle. [17] [18] In 2012, Super Soaker made two motorized water guns: The Lightningstorm, a reproduction of the Thunderstorm with added accessories, and the Electrostorm, a smaller motorized gun.
