The bodywork is a water-tight composite construction of top and bottom halves- hull and upper deck- hung from a frame of alloy extrusions bonded and riveted together. The running gear starts more conventionally- a mid-mounted engine driving the rear wheels through an automatic five-speed Jatco gearbox. But then it gets interesting. The output drive employed by Land Rover to power a second axle is put to use driving a water jet with 2200 pounds of thrust. ven the cooling system is complex, with a conventional air-cooled water radiator for road use and a water-cooled heat exchanger for boat use. The suspension defies motoring convention, too. Basically it is wishbones front and rear, but to switch into water mode, the wheels fold up into the wheel arches. Switching from road to water takes just a few seconds as a pushbutton automatically activates marine lights, deploys trim tabs, switches to marine drive and folds the wheels. A bunch of sensors ensure that the folding action is never repeated on land.
