engine question 2bbl or 4bbl carb

[bigeasy1]

Thanks all.I want as much power as possible,but i also want a smooth trolling speed out of it.
I'don't want to get too radical,and end up with an engine that idles like a race car.
It's primary use,other than getting me to a fishing location quickly,will be to be able to troll at 2.5 to 3.5 mph smoothly for several hours at a time.
