A waterjet propulsion apparatus comprises a motor 7, an impeller 6, driven by the motor via a drive shaft 8, and a power source. A fluid flow-path 10 is formed through the apparatus, the flow-path extending from at least one fluid inlet 9 through two propulsion passages 3, each propulsion passage extending from a propulsion inlet to an outlet 4 located at the rear of the apparatus. The impeller is located within the flow-path, after the at least one fluid inlet, and before the propulsion inlet of the each of the propulsion passages. The motor is located outside of the flow-path, between the two propulsion passages, and behind the impeller. The apparatus provides a compact and lightweight construction that can be used as part of a personal marine propulsion device 1, that can be used by an individual.
