A self-propelled water vehicle has a structural assembly which includes an elongate, water-tight hull adapted to provide seating for one or more persons along the top thereof and means, such as propellor or jet unit, for propelling the vehicle along the surface of a body of water. A control housing disposed at the forward end of the hull contains drive means operationally connected to the propelling means, and also encloses a steering control mechanism connected to a pair of pontoons disposed at opposite lateral sides, respectively, of the forward end of the hull. The pontoons are pivotally connected to the vehicle by support means. The vehicle is preferably constructed for conversion to a snowmobile by replacement of the pontoons and the water-tight hull, respectively, with pairs of skiis and an elongate snowmobile hull having endless track propelling means attached to the bottom thereof for propelling the vehicle over snow. In fact, existing snowmobiles may also be readily converted to the vehicle of the invention by use of the disclosed structural assembly.
