An Amphibious Vehicle (AV) is capable of planing with less power than prior similar size amphibious vehicles and using mostly off-the-shelf part. The AV uses an outdrive and propellor instead of a pump, and also include leading rear wheel well flaps which are spring biased forward against the hull bottom for on-road use, and pivot back to fill a gap between the hull and rear tire, reducing drag during in-water use. The combination of the propellor and wheel well flap allows planing with less horse power. An engine faces to the rear and either reversing differentials to reversing carrier and hubs provide correct wheel rotation. A reversing gear box attaches to an engine front and reverses rotation providing correct rotation for an outdrive and propellor.
