I have a 03 30 ft Daytona with bone stock 525's and getting to do some long distance travel on Texas coast. Weather finally breaking and going to take it out this weekend and start my calculations. Hoping for 2 mpg at 3,500 RPM. I now have new 34" 5 blade. I tested once during winter with these props on and was getting 75 to 80 mph at 3,500.
This is my first cat and have no knowledge of this. Am I way off at hoping for 2 mpg?
Let me know what MPG your getting no matter what your motors are. thanks, chuck

I think your probably pretty close, i have a 33 with twin 500 efi and i get at least that unless i am really beating on it. Haven't done alot of long distance running other then poker runs.
