ABSTRACT:
Damaged screw propellers are repaired by use of hollow, thin-walled envelopes, each envelope having surfaces corresponding in configuration to an outer portion of a screw propeller blade. Each envelope is located on a blade, and a workable material is interposed between the damaged blade portion and the hollow interior of the envelope. The workable material and the envelope become an integral part of the blade to substantially duplicate the original configuration of the blade.
