The numbers you posted are pretty accurate to most. There are a few faster and there are a few slower as with most models. Mine runs out @ 69.7 with two and a touny load, I an 06 with a 26 Trophy and am at 5500 rpms. With just me and light gear the best I have seen is 72.9 that was with water temps in the low to mid 70s. I thought about trying 24 or 25 Fury prop to see what the numbers would look like, but I do know mine does not like the 26 Tempest. It didnt seem to matter I did to jack plate or load it just was not good for me so I swapped to the Trophy and loved it. The four blades handles the rough better, heavy loads, tight turns, and was just all around better for me. I too put most of the tackle in the back compartments to put less bow weight, that seemed to help a fair amount as well. Sorry to be long winded but I know what you are going through. Good Luck and Tight Lines! Robbie
