You do realize that Silent Hunter 5 is "U-boats in WWII" simulator and not a "diesel engine" simulator, right?
Based on your mod requests, (
better diesels,
new motor sounds,
prop rotation,
reduction gears and
idling engines) I hope you can see why I'd be led to ask such a question.
I just think you might be missing a lot of the game play in SH5 by being frighteningly fixated on just one part of the sim.
