Well, I've been through Stock and Operation Monsun, and they are the same... I had never noticed that before. Lurker's Type2 in OM is different, in that you are looking at the other end of the boat by default in the control room, compared to the 7 & 9 models, but when you accelerate, the "front" of the boat picks up (the end by the Officer of the Deck), and the sound of the engines seem to come from the front. I can't quite tell when in the conning tower, but it also seems to be set-up the same way, although it is difficult to tell which way is supposed to be "front" and "back" there, as far as the sound direction goes. If you get into the AA gun position, it is also difficult to tell, since it almost sounds like the engine exhaust is right below that position. We'll have to wait for someone more familiar with the situation to come along and comment, but it definitely seems "backwards" to me...
