The invention is a direct replacement for conventional propellers on aquatic vehicles that utilize them. The cincture ( 26 ) ( 26 A) being a integral part with the propeller makes a significant improvement over conventional propellers. Being so manufactured means that it can be conformed to virtually all types of propeller applications. Such as mounting requirements, the number of helical screws ( 20 ), their pitch and direction of rotation, and rear or forward mounted propellers. The cincture ( 26 ) ( 26 A) being of one piece with the propeller means it is of the same material (plastic, aluminum, stainless steel, teflon, bronze, etc, etc.) as the propeller. Giving an enhanced performance and safety capability in a single article of manufacture for each desired application. Being beneficial not only for the owner, but the aquatic vehicle and its surroundings.
