Yeah, I keep my boat out of the weather. The floor is sturdy and dry.
Surprisingly, (knock on aluminum) I haven't found any leaking revits. After I rebuilt the transom 4 or 5 years ago, every time I took it out, not even a drop of water in the bilge.
This last four day trip was in semi rough water in Astoria and had some splash coming over the bow when plowing forward.
But still, the foam does appear to be soaking any of it up. I pulled a bunch out and it's all dry.
