Abstract:
A screw attachment for a weed-trimmer, which comprises a lower shaft housing with a proximal coupling to correspondingly mate and engage a distal mid-shaft coupling of an upper part of a motorized weed-trimming device; and a distal termination with a propellerâ€”such that when coupled, said attachment and the upper part of the motorized weed-trimmer can form an outboard motor for watercraft, and said attachment can be reversibly coupled to the upper part of the motorized weed-trimming deviceâ€”wherein said attachment further includes a propeller core as part of a propeller-containing attachment, to which the propeller is attached, and within which is a transfer shaft having a transfer shaft receptacle for receiving and mating with a lower coupling to a flexible core wire in the lower shaft housing such that the transfer shaft and a distal portion of the flexible core wire with the lower coupling are mated in an in-line relationship; and a keel core for registering with the propeller core as well as receiving the lower shaft housing.
