If you submerged it you still have a lot of work to do. All gear boxes and the front and rear diffs as well.
Check your fuel tank for water.
Since it is running you still may have moisture in the dizzy and some of the wiring.
Be happy it runs but still some more work to get it all cleaned up.
When you drain the gearboxes and diffs you will see what happened to your go power. The front will fill up not much to keep the water out. The trans and T-case are pretty good but need to be checked.
The fuel may burn but barely and the electrical and the dizzy may also harbor more moisture than you can see.
You can use a hairdryer on the cap and wires but the dizzy has open areas below that hold moisture and will send it right to the top of the cap again and again. Spray some WD-40 on the cap when your done.
