Currently, top speed (Full Throttle) is 120 RPM and around 12 Knots.

And minimum speed (Zero Throttle) is 0 RPM and obviously, 0 Knots.

However, I've got no clue how to make it reverse, as in, that when going below the "*0*" displayed on the Throttle, the submarine would go in reverse.
Any clues on how can I work on this?
Thanks in advance!!
