I am running a Bravo 1 FS 25″ with all 4 holes plugged on a 17 Sabre FTD DC, Fortrex, and Yamaha 175 SHO. Its been hot since I installed the prop, but with temps in the mid 80s to mid 90s and 30 gallons of fuel, full load of gear, solo, Ive seen 69 mph at 6K RPM. In cool weather, Im sure it will do 70. The main thing with mine is that I am out of the hole in under 3 seconds, no blow out, and the mid range acceleration is unreal. I will happily give up a mile or two an hour for the mid range performance. The boat will stay up at speeds down to 20 mph. 3″ PTP, but Im still playing a little with that setting. Handling is great in all conditions, especially rough water. Prop lifts the whole boat out of the water without too much stern lift. Trim up and the boat literally flies.
