I currently own a 1979 checkmate eluder with a 150 Evinrude motor on it. I recently discovered that I have a bad cylinder on the Evinrude. I am looking at replacing it with a 1998 mercury 3.0 litre 225 motor. I am running a jackplate with 6 inches of setback. I would like for some of the more experienced checkmate owners to tell me if my transom would support the motor. I would really hate to drop a motor in the river and tear the transom off my boat. Thanks in advance.
