Air Boat

Chevy 350 motor with a Rotator drive. Rotator drives are some of the best choices for airboats because the patented drive system in an airboat with the propellers rotating in opposite directions and driven by coaxial shafts. This arrangement has many advantages, among which are:(a) Noise reduction, since each propeller can turn at a significantly lower rotational rate to achieve the same speed as a single-propeller system;(b) Elimination of torque, allowing the airboat to ride flat, since the counter-rotation of the two propellers yields a zero net angular force on the airboat;(c) Increased efficiency, since the trim tabs on the rudders, which decrease thrust, can be eliminated, and since the distal propeller catches air turbulence "swirls" created by the proximal propeller and converts them to useful forward thrust; and(d) Increased durability and safety, since propeller breakage is greatly reduced, owing to the forces borne by them being cut in half. This boat was purchased by my father who has passed away, it is running and ready for a new home. Chevy 350 C.I. engine with a Fiberglass hull, and a Rotator drive.
