I've searched the forums here but have not yet seen an answer to this specific question. I'm wondering about whether or not it makes sense to use the same kind of technique on my transom holes that I am using for the deck holes. For the latter I am removing wood between the fiberglass skins using a Dremel router bit (as per Mainesail's method), taping below and filling with epoxy and redrilling. But the transom on my 23-1 may not have an inner FB skin attached to the inside face of the wood.
The gudgeon holes go through the outer fiberglass skin which is backed by a vertical wood plank (factory installed I believe) which seems to be about 7/8" thick. This plank is painted but there doesn't seem to be a fiberglass skin on the other side. I will be using two 1/4" thick aluminum backing plates when I reinstall these.
The new swim ladder (and outboard bracket) holes will go through the outer fiberglass skin, perhaps 1/2" of wood and then what is either another fiberglass skin or paint. I will be using large 1/4" thick aluminum backing plates when I install these.
So should I core out the wood and fill with epoxy even if there may be no inner fiberglass skin? Any suggestions about filling vertical holes.
Many thanks,
