Yep, three on each side, app. 1.25" by 3.5" glassed in. The original scuppers were 1.5" hose, two on each side, plumbed to one 2" seacock below water line. Glassed them in as well as two other holes for unused transducers. I like to get rid of the water on deck asap. and I like the look and simplicity of them. Should be able to post some pics soon when the plastic comes off after painting.
This is exactly what I am planning to do on my boat (same design of drains now and I am planning to cut through toerail and get rid of the drain-hose-thru-hull mess).
Did you do the work yourself? How did you go about cutting the holes etc. Any advice on the process would be appreciated.
