Look to see if airmar makes a tilted element for your FF. Then you won't need a fairing block.
Younggull and I (mostly Younggull) installed mine last year in about an hour or so.
Pretty straight forward.
Make sure the hole is even (may have to file down so the ducer sits flush in the hole.
Then run the cable thru and do a dry run of the install.
Once you are happy with the way it is sitting, slap some 4200 on the lip, mount it and tighten the nut hand tight.
Next day go back with a BIG ass wrench and tighten the nut all the way.
That's it.
If you go fairing block, I imagine it is a lot more work and a lot is involved.
The tilted element is pretty flush with hull, so none needed and mine works GREAT!
Toughest part was drilling a 3" hole in bottom of boat, but beyond that, it was fairly easy.
This is prob what you need:
