First off this test was on a G23 with the ESP package and a 250HP Verado. Tested the Revolution 4 14 5/8 x 15 compared to the Enertia 15x15. Conclusion the Enertia is a better overall propeller in terms of efficiency and lower prop slip numbers. It produces better mid-range and top range versus the Rev 4. It exhibits much more bite than the Rev4 particularly from 3000 RPM up while the Rev 4 continues to slip badly until it gets above 5000 RPM. Interestingly both props turned 6000 at WOT. The larger blade area and slightly larger diameter of the Enertia seems to offset the extra blade of the Rev4. in terms of load. All numbers recorded digitally and off GPS. Here is the data:
