20'MA Bracket or Raise Transom

[TJS]

I have a 1978 MA 20'. I just dropped it off for a total restore and was going to just raise the transom to a 25". I am now on the fence towards closing in the transom with a bracket I have read a lot of threads on this site about this but just don't want to spend the money and have it ride badly. I am thinking either a etec 115 or a Zuke 115 or 140. I do want the bracket. Any insight on this would be very helpful. I have a couple of weeks to decide. Thanks for the help.
