Hi Easton - no, I had a quiet winter for boat repairs; the transom cap remains as I 'temporarily' finished it last spring.
That being said, the epoxy cap itself is perfectly functional - it should be robust enough to seal up the transom for the life of the hull. The black plastic transom top cover that I reapplied looks pretty rough - it broke on removal, and the crack is kind of obvious. The aesthetics of this have bothered me less with time.
I plan to assess balsa core condition in the floor this coming winter, and remediate as needed. I may apply a new transom top cover at that point.
As Clay wisely counselled early in the thread - as it's currently boating season (and Yukon/Alaska summers are awfully short), it's worth carefully assessing whether time-consuming repairs are necessary right now, or can wait until this winter. Depending on your specific scenario, there could be low risk in waiting.
