SCX is a good mod and if I was you I would persevere with it a little while longer before uninstalling it. If I were targeting a surface ship, after getting a good TMA, I would leave the run depth of the torpedo at 200 feet and not bother altering the floor (unless there are submerged vessels in the vicinity that you don't want to hit or you are in shallow water) and ceiling settings and set the torpedo to go active at around 2,000 yards before it reaches the intended target. I have missed targets with active MK-48's in SCX but they tend to be submarines.
