I should have mentioned I used a Moeller drain tube flanging tool, 1 inch OD, part no. 020700-00, and a Pittsburgh mini tubing cutter, part no. 92878, sold by harbor freight. You do not want to over-tighten the flange tool, as this will cause the drain tube to split. Tighten firmly the flanging tool enough that 1-2 mm of caulk is visible between the tube and the hull.

I personally like the contrast between the clean brass tube and desert tan gelcoat or white gelcoat. Nothing wrong with the way hullinthewater did his set up, since he used paint, not gelcoat, on his hull.

I prefer not to use epoxy on my boat because I do not like the way epoxy causes the gelcoat to spit after a few seasons.
