Abstract: A drive train for an amphibious vehicle provided with a propellor disengaging mechanism aft of the transfer case, thus allowing the output drive shafts to be continuously driven at all times. The drive train includes a motor attached to a transmission which is attached to a transfer case. The attachments are accomplished by rotatably coupled drive shafts. The drive train transfers rotational movement from the motor to the transmission, then to a transfer case where it is output to the various drive shafts enabling the vehicle to be propelled on land and in water.

Abstract: A passenger seat for a vehicle which travels over or on water includes a base attached to the vehicle and for supporting the lower extremities of the passenger. A seat back extends upwardly from the base and supports the back of the passenger. At least one life vest constitutes a portion of the seat back. The life vest is capable of being removed from the seat back to provide flotation assistance to the passenger.
