2) This embodiment includes three modes of embodiment A, B, C. The main difference is the location of the engine 122, how power is transferred through the engine 122 to both marine and land travel.

3) In all embodiments, the connection method of power transmission is not limited, that is: the connection can be realized by direct connection or by the aid of transmission shafts, couplings and the like.

4) In all embodiments, the number of axles of the amphibious vehicle 10 is not limited, and may be two axles, three axles, four axles or more.

5) In some embodiments, the technical aspect of the front axle 128 is not limited.

6) In all embodiments, the specific number of the water jet propulsion devices 110 is not limited.
