Thank you Bill, that's realy briliant.
Now, my only speed indication is SOG from GPS and that is good enough. For the Ultra Sonic Speed from NKE, I would have to drill a new hole the get SOW. I think I am quite happy with SOG, even with some log-errors with strong curents. I will contact Tinley. What's the best contact, Sarah was her name?
If I want to upgrade my Hydra System to NMEA, would it be good enough to upgrade ONE FFD or do I have to do that with all components (2xFFD plus Processor)?

It sounds like you may be looking for another option...
One option is to display SOG on the analog B&G cockpit gauges and on the Hydra FFD rather than SOW by installing a NMEA paddlewheel.
The NMEA Paddlewheel device connects to a data port on the GPS, reads the GPS NMEA sentences and finds SOG. It then translates that SOG into B&G language as SOW. If you are a sailing purest, SOW may be important to you if you must know how much current is impacting your SOG, but remember SOG is what really counts and gets you where you are going.
This solution may be the best for you. It is simple to install: 2 wires connect to 12VDC at the Hydra toggle switch, 2 wires connect to NMEA data OUT on your GPS and 2 wires connect to the B&G computer at the same place that sonic speed or paddlewheel connect.
The NMEA Paddlewheel converts NMEA from either a GPS or electromagnetic log to a paddlewheel output suitable for connecting directly to an instrument system, such as a B&G Hydra/Hercules.
