Hey BigAl, I live over in Bay Saint Louis. Just got me a V20 last month. Has kept me pretty busy getting her right from just sitting around not being used. Nice to know some others around here have these boats because I haven't seen any. Mine is an 1986 Cuddy with a 175HP V6 Mercury. The consensus is 150 HP is perfect, and I agree, but it is nice to know I have that extra 25HP to spare if needed. Mine cruises anywhere from 30-35 on the GPS but have had it up to 43 on the river. Haven't worked on that motor you have but I'm learning a lot about this old Mercury. What sort of troubles your motor having?
