A personal watercraft (10) comprises a floatation platform (12) and a separate module (14) including a water propulsor driving crank mechanism (22) and a keel (38) mounting the water propulsor. The separate module (14), when mounted to the platform (12), extends at right angles to the platform with the keel (38) and propeller (40) extending below the platform (12) and the propulsor driving crank mechanism (22) extending above the platform. The separate module (14) is readily separable from the platform (12) for ease of storage and transport.
