From my experience with just trying to drill and fill with west system, the attempt yielded poor results. I can see how a vertical transom could be filled with Gitrot or something similar, but relying on thickened epoxy to penetrate a core in an area that is sporadically wet(deck, cabin) is futile. Even when I followed Casey's instructions to the "T", when I decided to rip it all out and re-core the right way I found the injection sites just had a small plug in the area of the dilled and reamed hole. A band-aid fix to a HIV problem at best. Commit, take the time and do it right. If you live close to your boat it isn't all that difficult of an endeavor, just a pain in the arse, sticky, step by step critical process.
