A tracked, amphibious vehicle, provides at least two, spaced, elongated pontoons disposed generally parallel to one another. A platform structure can be supported by and structurally connects the pontoons, the platform structure including a transom and a lowermost generally horizontally extending panel. A continuous, endless belt can encircle each pontoon engaging bogie wheels on the pontoon. A supplemental, marine drive assembly includes a hydraulic motor having a shaft with an axis, a propeller shaft having an axis, wherein the motor axis and propeller axis are aligned. A universal joint connects the hydraulic motor to the transom. A housing includes a sleeve that contains the propeller shaft.
