All Acme propellers are engineered, manufactured, inspected and shipped directly from Acme’s U.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. Boats using Acme Propellers are breaking out of their old envelopes and discovering their true performance potential – directly out of an Acme box.
