I have a 27' Signature, bare hull it weighs about 2,000 pounds and I'm putting a 454 mpi with a bravo one out drive and I have the installation manual but its a little vague on setting the height I've measured other boats and there all a little different any help would be great thanks

I would set the X dimension at 17". Thats the factory setting on a 28 Pantera. Your hull should be pretty similar.

Thank you 17 inches is an inch higher than the manuel and Im sure you know more than I do, I'd love one more persons input anyone else? Thanks Bman
