S. facilities. Acme's CNC process provides the most accurate method for consistently producing propellers to the correct diameter, pitch and cup, etc. Through this process, Acme can "dial in" to make incremental changes in any or all of these elements, which enables the development of an optimum propeller for each specific make and model of boat.
