Welcome to the site! These guys are great. Unfortunately my V20 project has taken a turn, but I still enjoy reading the site. I will actively look for a Center Console in the spring when I purchase another boat.
I started my transom repair from the top cap with a chain saw as well. The biggest tip I can give you is to get a big chainsaw. I have the 25" transom and when you figure in the corners (where the transom meets the bottom and sides) you need atleast 30". I couldn't find one of those at my local rental place. Your up in the NE so you probably have better access to one up there. You'll be surprised at how hard it is to remove some of that wood in areas of a "bad" transom. Its relatively hard to cut into the skin while skimming the sides of it and removing the "heart" of the transom...I never reached the bottom or sides (due to length of chainsaw) so I can't speak to that.
Also I had settled on the Nida-Core product for my project. I believe their website is Nida-core.com. I think you can find a local supplier there. It seemed to be the most accessible and affordable.
Good luck to you. Dont forget your Personal Protective Equipment!!!
