  • Selectable air propeller drive system
    Patent number: 6893302
    Abstract: An airboat and selectable drive system for an airboat are described. The airboat may be configured for mounting an engine either high or low in the hull of an airboat. The selectable drive system is connected to the engine. The selectable drive system includes a transmission interconnected to an air propeller drive. A clutch has three positions to include forward, neutral, and reverse. The air propeller drive rotates the air propeller in one of two directions based upon the selected position of the clutch. The drive system has the capability to rotate air propellers at different speeds. The reverse speed of rotation of the air propellers may be higher or lower than the forward speed of rotation. The modular design and simplified drive system is easier to assemble and align for both configurations.
