Ideally I'd love to get rid of the 3s and put 5s on it but can't find a buyer for the 3s, it's not so much that Im trying to gain speed just reliability. I don't want to be rebuilding drives all the time. These baby blower motors combined with the weight of the boat is enough to destroy bravos and figured since the 3s are sitting here in my way I'll put them to use next year

If you are at 18" with stock length Bravos, an x of 20.7/16" will put you at the same height. I would a least go with 23½"-24". You can always use a 3" spacer and get down to or close to current prop depth if needed, but 23½" will suface your IIIs and that is what they were meant to do. With the big cleavers, you may even be able to go higher. Next question is, do you have room under your hatch?

X dimension
Go for the SSM#3s and a high x-dim. Much stronger than a bravo and they run surface props. An interesting thing could be to see if you could in any way swap yor IIIs for Vs. The lower drive x-dim makes for easier and better installation. If you are running biggish power, your bravos are going through hel! on that boat and are on borrowed time anyway.

Measure perpendicular from the crank shaft or even more precise, input shaft centeline to the bottom of the boat. Keel or pad if it's a single and just the bottm if a twin. When I measure x, I use a straight edge on the bottom and then measure from the point where the input shaft centerline exits the transom. You don't want to get your transom angle involved. If you have boxes, you'll need to measure from the box and not the transom. Due to the transom angle on some boats, boxes will change the x, since the transom angle is not always the same as the box angle. Ie. a straight IMCO box with a 13* angle on a 15* transom will lower the x slightly and vice versa.

Just did a little drawing viewed from the side of a boat, it very rough, but gives a pretty good idea about how to measure. The red thing is a straight edge and the blue line, will it goes without saying. The circeled spots is where to measure.
