The new SCAC plate assemblies are provided with blocked ports at the bottom to prevent sea water from contacting and corroding the Transition Plate. When corrosion is found, the new SCAC plate assembly should be used and the Transition Plate should be replaced.Adaptable To: The following parts are adaptable to the machines within the listed serial numbers, and are effective with all machines after the listed serial numbers.
