Torn out through-hull drain please HELP (with pix)

[Trayder]

I am 99.999999% sure that fitting was an afterthought by the previous owner. Most of the original 20'cc livewells I have seen have a 4" hole in the transom with a removable pie plate and drain holes for filling and these were on the port side.

Since what you are showing is on the starboard side (I think hard to tell from pictures) i think someone put hat hole in afterwards for something else, wash down sys perhaps???

If you want to keep it the hole as a thru-hull do as capt loyd suggests with a bronze pick up/thru hull and a ball valve inside to turn it off.

If you want to fill it you will have to grind/feather the outside back and lay glass. What concerns me (not really but more effort will be needed) is the liner from the livewell on the inside of the hull. I would want to lay glass inside the hull, under the livewell liner. So you would have to cut out a section of the liner to lay glass from the inside.

What I an stumped on is the fact you have an inner liner for the livewell (not doubting this) but on my 1969 when you lifted the aft hatch boxes you had access to the inside of the hull, there was no liner?
