The Arco 4010 is a high-output 12-volt marine and industrial alternator. It is part of Arco's "Zeus A225S" series, designed for demanding applications that require rapid and efficient battery charging, such as on large boats, RVs, or commercial/military vehicles. It is a dual foot mount where the feet are 3.15" apart, this is often known as a Yanmar mount because it is typically found on those engines.
