I currently run a 24 pitch Fury 3 and Fury 4. (Both worked by Ronnie Gilbert) The 3 blade will run 76 mph with a light load but can be sluggish with a full tournament load. It's also only spinning 5600-5800 rpms. That's well below the 6200 Mercury recommends for optimum performance. I know Bass Cat now recommends the 23 Fury 3. They're tough to come by right now. My 24 Fury 4 drives like a dream. Boats lifts great and is responsive. Mid range has pop but top end bottoms out at 71 mph. Again.... I'm only turning 5800 rpms. Has anyone tried the 23 pitch Fury 4? I think gaining 200 rpms might improve the overall performance.
