my friend has a 2007 puma with a new 250 mercury pro xs. setup like yours (3 12″ graphs, 112 ultrex, poles, livescope and mega 360) he runs a 24 fury. he sent it in to Croxton for extra PVS holes added to aid in summer time holeshot and Croxton doctored it up for a bit more lift. itll run 73-75 with 500 lbs of angler, full wells, all compartments full of tackle.
he previously ran 26 and 25 furys with his 250 Merc Racing optimax
