self bailing scuppers

[Billsseacraft]

I have ran into a snag with my self bailing drains. The drains on my boat go through the floor and out the bottom of my boat. The problem that I have is that the holes going though the bottom of the boat are around +1 5/16 of an inch and the 1 1/4 tubes I have got don't fit just right and at best seem cheap and flimsy. The other issue is that one side of the boat (from the floor to the bottom of the boat) is deeper than the other one side top to bottom is 4.5" and the other is 3.875". That is not the real problem the problem is the sloppy fit of the drains. I don't want to do the job half A@#ed. Ok, would anyone trust using a piece of 1" pvc pipe secured with an epoxy (West Systems). The outside dimensions of pipe are almost perfect to slide through the hull and into the floor of the boat. I thought that I could wet out all of the fits with epoxy and then leave the bottom of the pipe recessed and fill with the epoxy and sand flush with the bottom. On the inside I could do the same finsh technique as the bottom. I'm really lost I have thought about running the drains out of the transom but I would have to remove part of the stringers to do so, and also I would never be able to tighten hose clamps under the floor. I want to do this right, the thought of being 80 miles offshore and having my boat sink gives me bad dreams!
