Weigh the contents and the boat. Calculate the area of the boat to be in the water. Take a cubic foot of water at 7.5 gallons of water at 8.3 pounds per gallon and .
The boat will displace the amount of water equal to its weight. Since the hull isn't perfectly rectangular and the answer would be for the load being equally distributed....like to offset the weight of your engine, move folks and gear forward, you ought to be able to get some idea as to its draft.
Tiller vs remote steering certainly plays into this calculation and makes a whopping big difference in how low the transom sits.....moving the fuel tank from behind the last seat up forward the length of the fuel line helps too.
Crappie boats are usually long and narrow. That works against you. Wide transoms help a lot in shallow draft floating.
If you are snow bound, it might give you something to do to pass the time. So lets kill some time. Referincing:

Boat 1165#, 10 gallons of fuel, engine 375, 2 avg. guys 350, tackle 150, livewell empty, beer....TBD = 2115#
Taking the hull assembled into a rectangular cube I estimate the average transom width (93-67)/2 +67 to equal 80" wide.
Taking the way the hull is shaped I am going to take 14' for the length. So looking at the area 1' deep for a cubic type measurement I come up with displacing 255 gallons which is only 34 cu. ft.
That quick estimate says that the water line will be 1/3 of a foot above the bottom or 4" draft. With 22" sides and what folks normally do, with the helm mid-ship which really helps,I would anticipate an 8" draft overall while fishing and folks moving about and all.
Underway, you will be deeper than that due to the transom sinking till up on plane....expect maybe as much as 12" plus engine. If you mainly idle along with the the engine tilted up that's one thing. If you want to hammer down on the throttle and get on plane where your skeg clearance might be 13" for the prop plus 4" draft, you are looking at minimum 2' depth for my best guess.
In coastal areas they use tunnel hulls for shallow water fishing where you can run on plane and get there in just a few inches of water. This is just a WAG but it is a set of numbers and something for you to think about.
