what is the best way to run 4.5 od dry tailpies through transom (dumps water ouside transom)?

Fred I wish you were around when I bought the Stelling rings with out gaskets for 250.00. for my old Scarab. I feel like I got raped all over again you posting those cheap prices

I got a set like that ,but having 55" tailpipes the wieght is to much for the soft gray silicon rubber, the tails would sag

PS I paid 65.00 for mine @#@#
