ABSTRACT:
A power train for an amphibious vehicle includes an engine and transaxle arranged North-South, driving front, rear, or all four road wheels. A power take off with optional decoupler and constant velocity joint drives marine drive. The power take off may be taken from the input shaft of the transmission, and may use a synchronizer. The transaxle includes a differential. The rear wheels may be set back from the differential outputs, with intermediate drives by chains or belts. A sandwich type power take off may also be used. In the four wheel drive embodiment, a power take off is required from the rear differential. Decouplers may be provided in at least one wheel drive shaft on each driven axle.
