For those of you that have this set up, or even with the 3.3L 250's...
I tried a set of Mecury Enertia 15X15P off a friends boat and realized I needed them. So I bought a set from Ken at Prop Gods this Spring
Hole shot to top end is perfect. WOT is exactly 6000rpms. The boat handles completely differently. The hull rides higher and drier and feels like I added 100HP. Fuel economy at slow cruise as high as 1.7mpg, more typically 24-26kt at 1.4 mpg. Rpms came up a bit vs traditional 17P, however GPH came down suggesting less load on the motors. In fact the motors sound different, like they aren't working.
I stumbled on these Merc props a few years back when I has a 23 gulfstream and 250 3.3L 4 stroke. In that case the Mirage 15.8X15P was the perfect fit.
Hopefully this helps somebody with their selection process.
