My shaft length... No not that one, silly.
I have a 23CC with a notched transom and the measured length from the top ledge to the keel is 27 1/2 inches. I currently have twins with 25" shafts and of course they are adjusted so that the cavitation plate is about even with the hull.
I've been looking to repower and find that 30" shafts are in short (no pun intended) supply, so the question is: How much adjustment is available on most outboards by just moving the motor up or down on the transom clamp? Is 2 1/2 inches too much to adjust if I go with a 25?

1 inch above preferred or no more than 1 inch below the cavitation plate from the bottom of the boat.
See ya, Ken

The 1" rule can be stretched but you would need a prop with alot rake and long blades like a Tempest,just a prop designed to run higher. I have that problem now but my motor is all the way down. This what I have now which a plain jane Merc and it won't pull the bow before it breaks lose, look at a Tempest and you will see the difference.
