Are you measuring vertically or along the flat of the transom? You should be measuring vertically from the plane of the transom top to the plane of the boat bottom. For the motor you should be measuring from the plane of the clamp top (where it meets the transom top) to the plane of the anti-ventilation plate...
Easiest way to make your motor an X-long shaft is to find a blown XL model. Otherwise you'll be hunting around for bits and pieces...

With a decent prop you're going to be fine. Most so called 20" transoms are about 20 3/4" anyway. And then the motor gets raised up a hole or two. If you get a 25" midsection you'll need a jackplate to raise it up high enough.
yes measured like you said, and seems engine is still to short, when boat is used it it performs great until you go for top speed or wot, upto 5500rpm its ok but push it to 6500 engine revs out and boat goes no faster.
