Yea, Gillie, the holes in my wood blocks were about 2" in diameter after I cleaned out all the rot!

So I just sealed bottom of hole, filled the whole thing with thickened epoxy, and then redrilled the hole, but I did use a lot of 5200 on the brass tubes. You do have a good point about eliminating the brass that will eventually corrode. I considered PVC like Big Shrimpin used, but that reduces flow area which I didn't want to do . . if you ever get a big wave over the transom, you're gonna want to get that water out ASAP! The brass tubes were easy and allowed min wall thickness and max flow area, so decided to stick with original configuration. I had previously replaced those tubes about 30 years ago, so I'll let the next owner worry about the ones I just did a couple of years ago! If I was redoing the boat however, I'd go with the Moesly design with the scupper lines crossing under deck and draining out transom on opposite side of boat. Denny
