What is the weight of the boat? My last boat DCB MACH 26 with twin 2.5 offshores (280 hp) ran a best of 106 mph. The skater 28's with 2.5's on the offshore circuit are running in the 110 mph range give or take a little. These boats are vaccuum bagged kevlar layups. Depends on the setup as well. We had to lower the motors on the mach because of water pressure problems which cost a couple miles an hour on the top end. If you can run external pickups off the hull and keep the motors as high as possible it will add a little on the top. The best props I ran were merc 15x30 labbed cleavers. With the extra hp you have you might be able to pull some 32's. Good luck. Chris
