The recent failure of the masthead unit for the Hydra 2000 ($1,000 replacement cost since I killed it trying to free the bearings) has gotten me to thinking about a phased replacement of the electronics. Right now all is well, but I do like the features found in the current generation of gizmo's.
The Hydra 2000 system, as far as I can tell, is not connected to the Furuno chartplotters or the Raymarine S3G Autohelm. I know Bill R has done some significant work to Bebe to make that happen, but that's not the case on my boat.
So, it seems I could replace the Chartplotter/Radar/Gyro combo without effecting either the Hydra 2000 or the Raymarine Autohelm IN THE SHORT TERM.
Since the Hydra 2000 is NMEA 0183, it could be plugged into a new NMEA 2000 Chartplotter, if I were to go that route. Since the S3G is old, and uses Seatalk, I don't know if it could be connected to a NMEA 2000 bus.
If the sounder fails (which seems to be a common occurrence), and I have the new Chartplotter installed, it would be simple to connect a new forward scanning sonar transducer into it.
I'm thinking of this since I've already put about $2,500 into the current system and like a car with 130,000 miles on it I don't want to keep putting money into it if the failures are going to accelerate. Has anyone tried a "phased approach"?
Any luck connecting the Raymarine S3G to NMEA 2000?
