ABSTRACT:
The invention relates to hand-insertable, rigid plastic cover for use with an individual boat blade of a propeller of an in-board or outboard boat motor wherein each cover of the invention is integrally formed as a single unit using of a conventional plastic material such as polyethylene. Briefly, the plastic cover of the invention comprises a pair of broad side walls of a tear-dropped or elliptically shape placed in a side-by-side relationship and terminating at a U-shaped closed edge or end wall but being open at a concavely formed, transverse open top to permit easily insertion over the leading and trailing edges of each blade. The shape of the broad side walls, the use of a U-shaped closed edge, the capability of the side walls to outwardly flex for insertion over the cross section of the blade, and the use of a rigid plastic such as polyethylene, permits the cover to be pushed over the blade from a position exterior of the leading and trailing edges of the blade using a section of the closed edge as the push region for the user's hand. Due to the sufficient stiffness provided by the invention, the cover can then be easily and safely advanced by the user to move the cover over the broad surfaces of the blade so that at least 80% of the leading and trailing edges of the blade are covered.
