Abstract
Abstract An amphibious vehicle is propelled by a conventional inboard mounted engine which is connected by conventional automobile transmission and differential mechanisms for driving a pair of wheels on land and also connected with a conventional inboardoutboard marine drive mechanism, all of the wheels being mounted on air suspension means which are pivotally connected with the hull to allow the wheels to be raised for marine use.
