74 25' SEAFARI with twin outboards

[0179]

please give me your 2 cents worth as I try to complete my project! I have gotten my transom redone and my twin engine gill bracket with twin 150 carb mercs are on the bracket. I was hoping that I could get some input from some of you guys that own 23's with twins on a bracket. I just want to know if you had to raise the deck height to allow for proper draining through the scuppers. I promise I will post my pictures when I get done. I've got a feeling that she may be the only 25 seafari in existence with outboards! Give me all the input or advice that you can. I'm in deep now and dont want to make any costly mistakes at this point. thanks in advance
