I wouldn't spend the money on this boat. A 25 ft. boat with only a 260 hp. small block will not make you happy even if you get to 350 hp. that is the max that drive can handle and still hold togeather. The only thing you will gain is maybe 5-7 mph but the boat will come on plane quicker and pull skiers better.. I suggest putting the money towards a different boat - possibly a hull designed for at least 60 mph stock.
