back the 20 inch offset with a piece of mdf board with release wax or a piece of melamine board. this backer allows you to layup up your glass and then unscrew leaving just the fiberglass to the height of the 25" side. do this on the inner liner and the outer liner, gring the new glass down even with 25" transom height and then do your pour. There are some good transom pour videos on youtube.
If you go back with a wood core then just put your core material back to a full 25" transom then glass the 20" offsets on the inner and outer skin.
When I came on this forum I hardly knew squat about any major glass work. I did ALOT of research on the internet and asked alot of questions. One thing I will say is to take your time,and learn all can about cloth weight and application, and additives and thickeners such as cabosil. these items are pretty important. these guys on here have a crap load of knowledge to be able to help you thru this build. I also joined other forums just to get other ideas and research material. good luck on your build we are all here to help you with whatever you need.
