cut out transome

[flounder]

I have a 1975 23 ft cc seacraft that I just cut out the transome and removed both gas tanks after replacing transome was wondering if I should put large scuppers in or will this be a problem. I plan on installing a hermco bracket and have twin 150 merc optis i know people have had problems with the scuppers but have not even used the boat before, do I need to raise the deck and finally does anybody have a mold for a bait well to go in the space between transome hatches. when I get a chance I will take some pic thankyou for any help.
