A propulsion system for a personal watercraft comprises a pair of paddle assemblies and a drive shaft extending between the paddle assemblies to induce co joint rotation thereof. A drive mechanism is coupled to the drive shaft and a pair of supports connect the drive shaft to the watercraft on opposite sides thereof to permit rotation about a common axis. The drive shaft is connected to the paddle assemblies by a releasable coupling to permit ready disassembly thereof. The paddle assembly comprises a central hub and a plurality of paddles coupl ed to and radially extending from the central hub. Each of the plurality of paddles comprises a front surface and a rear surface, wherein the front surface of the paddles is oriented away from the personal watercraft when the paddle assembly is positioned adjacent thereto. The propulsion system is separable into a plurality of individual sections and is thereby portable.</ SDOAB>
