Abstract
In one possible embodiment, a propeller adapter is provided which includes a base having at least one fastener hole therethrough and a propeller alignment boss extending upward from the base. Opposing capture walls extend upward from the base, each of the opposing capture walls have a lip extending inward to capture and retain corresponding opposing outside edges of a root portion of a propeller therein upon seating of the propeller root portion between the opposing blade capture walls.
