V20 Fish W / Twin 150's !!

There is a guy here in savannah with a full transom cuddy that has a 300 GT johnson on a full floatation bracket. It does a good 70. My old V-20 with a 225 merc and 24pitch four blade chopper would do a solid 60. Having grown up with an offshore boat racer as a father, I like to go FAST, but then again who doesnt?
