I have a 1988 Bayliner 2655 Ciera with OMC 7.5 engine / sterndrive. The only numbers I can find are on the sterndrive which read: Model 985275, Engine: 7.5 Lit. Seriel Number: T0586571. The engine is Ford based. Can anybody help how to find which engine model this is. Thanks. I need pushrods and having difficulty locating...
