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.

1. 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. 2. A power train as claimed in claim 1, adapted such that the engine can be positioned between the rear wheels and the front wheels of the vehicle.3. A power train as claimed in claim 1, wherein the power take off is provided by the transfer drive which is adapted to drive the marine propulsion unit by means of a second drive shaft which runs substantially parallel to and below the engine.4. A power train as claimed in claim 1, wherein the power take off is provided by the transfer drive which is adapted to drive the marine propulsion unit by means of a second drive shaft which runs substantially parallel to and along one side of the engine.5. A power train as claimed in claim 4, wherein the first drive shaft runs along an opposite side of the engine to the second drive shaft.6. A power train as claimed in claim 1, wherein the power take off comprises a further transfer drive which is fitted to, and driven by, the first drive shaft.7. A power train as claimed in claim 1 wherein the marine propulsion unit is a water jet, or a marine screw propeller.8. A power train as claimed in claim 1, wherein a decoupler is provided in the drive line from the power take off to the to the marine propulsion unit, to enable drive to the marine propulsion unit to be selectively coupled and decoupled.9. A power train as claimed in claim 1 wherein the first drive shaft is adapted to drive the rear wheels of the vehicle via a rear differential.10. A power train as claimed in claim 9, wherein the transfer drive also drives a third drive shaft which is adapted to drive the front wheels of the vehicle through a front differential.11. A power train as claimed in claim 1, wherein a decoupler is provided in the drive line between the transmission and at least one of the driven wheels, such that drive to the at least one driven wheel can be selectively coupled or decoupled.12. A power train as claimed in claim 11, wherein the at least one decoupler is arranged for coupling drive to a wheel drive shaft, the decoupler incorporating a synchromesh mechanism and being combined with a constant velocity joint.13. An amphibious vehicle, characterised in that the vehicle comprises a power train as claimed in claim 1.14. 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, and the transfer drive is 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, the drive for the marine propulsion unit is provided through the transfer drive, and the power take off comprises a further transfer drive which is fitted to, and driven by, the first drive shaft, the arrangement being such that the engine can be positioned at least partially forward of the rear wheels.
