Abstract
The invention relates to a drive system, and method of forming the same, for a craft in water, said drive system comprising a drive means, one or more shafts which are provided in connection with the drive means via one or more gear assemblies and at least one of said shafts having a free end with location means to allow the same to be located with a propeller of the said craft to impart rotational drive to the propeller. The location means are at least partially located within a port in the body of the propeller and intermediate said location means and the walls of the said port there is provided a substantially non-conductive deformable material sleeve which separates the propeller body from the said shaft and retains the propeller body in drive engagement with the location means. The provision of the sleeve allows the electrical isolation of the sleeve and propeller, allows a more robust connection between the propeller and drive means and reduces the impact of vibration on the operation and efficiency of the propeller.
