A nautical propulsion device for an amphibious vehicle wherein the rims (2) of the driving wheel tyres (1) are provided with vanes (3) rotating with the wheels. Each of these wheels comprises, in the region where the liquid leaves the vanes (3), an open delivery channel (4) adjacent to and facing said region, and a delivery pipe (5) with its outlet facing backwards with respect to the desired travelling direction. If the driving wheels are also guiding wheels, the vehicle may be steered through the water simply by turning said wheels without any other drive being required. Said wheels act as pumps using the reactional fare to propel the vehicle during nautical use.
