This is not really a prop... and it does not do what you think is looks like it is doing.

Yes, it is there, and it is probably used on all 688's now. I can not tell you what it was called as it was (and for all I know still is) a classified item. I know our boat was testing working hardware of the original concept design. I can tell you for a FACT I know what it is, what it is there for, and how it works.

The reason for it goes beyond the scope of a sub sim.
