hi again,

I've got yet another interesting question which some of you with more
experience can likely say a few words to... I was out testing my project
boat on the trailer, and ensuring the bilge pump would work right by putting
the plug in the boat and filling the back end with a few inches of water.
Well the bilge pump works great, however, when putting the boat plug in I
felt that the wood between the inner and outer fiberglass was a wee bit
slimy and the hole perhaps not as narrow as I'd like to have to ensure the
plug stays in securely.

What can I do here to fix this up?

An idea was to get some fiberglass resin and put a thin coat in the hole as
to seal things, narrow up the hole width, and strengthen the inner hole for
the plug.

Or perhaps a newer plug would be a big thicker...

btw, the boat is a 70's era 15.5 fiberglass.

I feel that the rest of the transom is fine, just this part around the hole
seems to be a bit questionable.

thanks
Chris

Most boats have a brass or stainless insert that is epoxied into the
hole. It basically looks like a short piece of pipe with one end
beveled out. This may be missing, and would account for the plug being
loose feeling. Also, the plug is usually adjustable, just turn the
lever a couple of turns, try again.
