I tried the 2" shortie with the box on mine but I don't think it liked the nose cone. I believe it works the best at neutral or slightly positive trim where step bottoms work.

My motor made 780 hp maybe more coming for this year I don't know yet. What you may notice is a loss in cruise speed If you raise the drive higher than where it is now. A five blade will help but it will tax the drive

Good luck, Jim

You must have the fastest 27 out there.
