A remote controlled self-propelled toy vehicle is disclosed which is capable of moving on a solid support surface and also on water. Two motors and a power source are mounted to the hull of the toy vehicle. Each motor drives, through a suitable transmission assembly, a drive wheel and a screw propeller. The drive wheels are disposed to come into contact with the solid support surface for operation as a land going vehicle, and the screw propellers are disposed for submersion in water when the toy vehicle is operated as a boat. Steering of the vehicle is accomplished on the solid surface and also on water by varying the power output of the motors so that uneven power output of the two motors causes the vehicle to turn. A suitable, preferably radio signal emitting remote control system and associated circuitry is provided to allow a player to steer the vehicle from a remote location.
