x-dim refers to the distance from the bottom of the hull to the center line of the crankshaft.

On a standard bravo the distance from the prop shaft to the input shaft is 21-13/16

I am assuming the 1" dimension you talk about is having the prop shaft 1" below the bottom of hull this would equate to a x-dim of 20-13/16.

If he meant 1 inch above the bottom of the hull the x-dim wouild be 22-13/16

Do a search this has been covered many times, I have one that is under the "Drives" section called "what is your drive height". I raised mine up 3" from stock, I think the x went from 15.25" to 18.25". All boats are different, too low too slow, too high and it will not plane off.

17" is the correct X for a 28 Pantera. That puts the propshaft height at about 4.75" below the bottom.

Single engine pleasure 28 Panteras need the X at 17" and thats even agressive. Any higher and its hard to carry the bow. You can go to about 17.5 or maybe 18 on a lighter race/poker run boat with no cabin.
