What year model boat? My old 2007 puma with a 225 would ran 76 unloaded (74 loaded) with the 26 trophy plus, but when I went to my 2012 puma ftd with the exact same motor I could only run 73 unloaded (70-71 loaded) with that prop. Switched to 25 fury and could run almost 75 unloaded. I had an issue with mine not turning rpms and ended up being that the bolt on the hotfoot backed out on me and wasnt allowing the throttle to open up all the way. I was only able to go about 65 with a load. Id check that first as it was a super easy fix and got me about 6 or 7 mph out of my boat when loaded.
