It seems to that I have spunned my props outward last summer om my Phantom 25 with twin merc 2.5 EFI's.

I felt the boat was running very flat and high, and it needed lots of positive trim. However, I only managed to test two different kind of props (Mirage Plus 27 and Bravo One 28).

Spinning in should create better bowlift and free up the hull. The downside can be a more unstable ride and problems docking.

The Phantom 25 is very weight sensitive and bowheavy. So I wonder how much gain I will get spinning in. On bigger V hulls 1-2 mph I have read.

I will use ET 28 pitch props this summer.

Any experiences out there?
