As I understand it the new transoms have no plywood...if the 2003 boat does not have plywood then the dealor and the representative at G3 have no idea what they are talking about?

I have not cut into the transom yet to check it out but will at some point to repair it. I will put the "How to Repair a Defective G3 Transom" video on You Tube. If it is not plywood then we will find out what it is?
