ABSTRACT:
A method and apparatus is disclosed for connecting a drive axle to a propeller. A drive member is configured to mount on a drive axle, a tubular member is coupled to the propeller, and a resilient members is configured to be positioned between the drive member and the tubular member. The drive member has an axis and includes a plurality of radially outwardly extending ribs. The tubular member is coupled to the propeller and has an axis and a plurality of radially inwardly extending ribs. The resilient members has an axis and is configured to be positioned between the outwardly extending ribs and the inwardly extending ribs. Furthermore, the resilient members is mounted coaxially with the drive member and the tubular member.
