Abstract
Power train or an amphibious vehicle having an engine, transmission, and transfer case position in-line with longitudinal vehicle axis towards the rear of the vehicle, with transmission output facing the front of the vehicle. The transfer drive drives the rear wheels via propeller shaft, which extends adjacent the engine to rear differential. A marine drive PTO (power take off) may be taken from a shaft from the transfer case, from the propeller shaft, or from engine crankshaft pulley. Marine drive shaft may run below the engine, or alongside it, on the opposite side of the engine from propeller shaft. Decouplers may be provided to the PTO drive, to at least one rear wheel, and on the optional front axle propeller shaft.

A power train for an amphibious vehicle comprising:
- an in-line engine and speed change transmission assembly adapted such that the engine can be positioned towards the rear of the vehicle with the transmission output facing the front of the vehicle;
- and a power take off means adapted to drive a marine propulsion unit located behind the engine;
- wherein:
- a transfer drive is provided in-line with the transmission,
- the transfer drive being adapted to drive a first drive shaft which extends rearwardly along one side of, or beneath the engine and which is adapted to drive a rear differential for driving the rear wheels of the vehicle,
- and the arrangement being such that the engine can be positioned at least partially forward of the rear wheels,
- and wherein the drive for the marine propulsion unit is provided through the transfer drive.
