Looking for info on a XR drive with I.T.S System. I know it changes the set back 5" I do believe? Does it affect the x dimension? Any info at all would be helpful as I have no experience with this set up. Thanks in advance.

its an 8 inch setback and will lower your X approx 5/8's of an inch.

Actually lower, or effectively lower?

What offshoredrillin said. If you are really looking to purchase a new ITS transom assembly, give BAM a call. They had a great price on that unit. And to complete the package, add the Zeiger ITS extension box to get the most set-back. Good luck.

On a 25OL you'll have to put a 2" shorty on to benefit from the setback.
