Thanks OC - PM sent. The 1-1/4" tubes have 156% of the flow area of the 1" tubes. I got 0.030" wall thickness from McMaster Carr since it was as thin as I could get - I don't think I can flare the 0.045" stuff; 0.030" will be challenging enough anyways. I think Moeller does not make the 1-1/4" brass tubes long enough for the scuppers. McMaster has 1-1/4 brass tube but I'm not sure if it is a marine alloy so I decided to add some 316 stainless to a recent buy and try it - maybe several times before I get it right. I'm not rushed for time since I haven't even finished the transom yet, much less started the decks.
