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