A single battery operated motor coupled to a transmission simultaneously drives both the 4 drive wheels and the water turbine. Power shafts from the transmission to the water turbine and the drive wheels are contained in isolated vertical risers extending above the water line so that the vehicle housing cavity containing the battery source, motor and transmission remain water-free without the use of seals.
