Instead, ports in the cylinder liners provide incoming air and exhaust. The two camshafts on the engine provide timing for two injection pumps per cylinder. Porting allows exhaust gases to be expelled and scavenge air to be taken in by a positive air box pressure. Intake air is provided by an engine driven Roots blower or turbo-supercharger. [4]

The airboat is propelled by a column of air generated by a propeller, with wind speed generated up to 150 miles per hour (241 km/h). Rudders attached to a control stick divert the air to steer. Airboats generally travel at speeds of around 35 miles per hour (30 kn; 55 km/h); modified craft can reach 135 miles per hour (115 kn; 215 km/h). [6]
At the bow of the boat are storage bags for equipment (foot pumps, extra lines, etc.) and a special fuel bladder, which can be of either 6- or 18-gallon capacity and which feeds the engine via a flexible hose. Deflated and rolled up, the boat and all necessary equipment can easily fit into the bed of a small pickup.
