Abstract
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.

An Amphibius Vehicle (AV), comprising:
- a chassis;
- wheels for on-road use;
- an engine carried by the chassis;
- an engine rear facing forward;
- an engine front facing rearward;
- a rotating engine crankshaft residing inside the engine;
- a transmission rotationally coupled to the engine crankshaft at the engine rear;
- reversing gears rotationally coupling the wheels to the transmission for on-road use, the reversing gears reversing rotation of the wheels;
- a reversing gear box rotationally coupled to the engine crankshaft at the engine front, the reversing gear box reversing rotation;
- and
- an outdrive and propeller rotationally coupled to the reversing gear box, the reversing gear box reversing rotation of the outdrive and propeller to rotation of the crankshaft.

- wheels for on-road use;
- an engine carried by the chassis;
- an engine rear facing forward;
- an engine front facing rearward;
- a rotating engine crankshaft residing inside the engine;
- a transmission rotationally coupled to the engine crankshaft at the engine rear;
- reversing differentials rotationally coupling the wheels to the transmission for on-road use, the reversing differentials reversing rotation of the wheels;
- a reversing gear box rotationally driven off the engine crankshaft at the engine front, the reversing gear box reversing rotation;
- an outdrive and propeller rotationally coupled to the reversing gear box, the reversing gear box reversing rotation of the outdrive and propeller to rotation of the crankshaft;
- an outdrive gimbal assembly fixed to the chassis of the AV;
- the outdrive pivots about gimbal bearings of the outdrive gimbal assembly;
- and
- the reversing gear box is fixed to the outdrive gimbal assembly.
An Amphibius Vehicle (AV), comprising:
- a chassis;
- front and rear wheels for on-road use;
- an engine carried by the chassis;
- an engine rear facing forward;
- an engine front facing rearward;
- a rotating engine crankshaft residing inside the engine;
- a transmission rotationally coupled to the engine crankshaft at the engine rear, the transmission drives both the front and rear wheels through a transfer case;
- the transfer case drives front and rear reversing differential through transfer case drive shafts;
- and
- the front and rear reversing differentials drive the both front and rear wheels through front and rear half shafts, the front and rear reversing differentials reversing rotation of the front and rear wheels to compensate for the engine rear facing forward;
- a reversing gear box rotationally driven off the engine crankshaft at the engine front, the reversing gear box reversing rotation;
- and
- an outdrive and propeller rotationally coupled to the reversing gear box, the reversing gear box reversing rotation of the outdrive and propeller to rotation of the crankshaft.
