Keep your Yamaha F25A performing at its best with this complete 20 hour service maintenance kit designed specifically for models produced from 2009 through 2019. Built around Yamalube 20W-40 FC-W outboard engine oil, this kit provides the essential components needed to complete your scheduled break-in oil and lower unit service.
