Default Raymarine A70D with Garmin GFS10 How To???

Hey guys, I'm trying to build a system to where I can monitor my fuel flow and overall fuel consumed through my Raymarine A70DD. I've contacted Raymarine directly and the enthusiasm from the technical department is less than impressing and marginally helpful. So, after many hours online I believe I have come up with a solution. I am hoping that somebody out there can say that this will work correctly or maybe point me into the right direction on something that will. Basically, what I think I need to do is purchase a Garmin gfs 10 sensor and link that back to the Raymarine through and an NMEA 2000 setup. Sounds great on paper right? Now, can somebodyexplain this to me piece by piece like I'm a 5 year old? Thanks for any help

In order for the GFS10 to work properly, it must be calibrated to your tank and fuel flow. Garmin uses proprietary pgn's to calibrate it. In other words, you need a garmin mfd or chartplotter to calibrate it on your network. Once calibrated, it will display on any nmea2k compatible device.

A couple of options would be to get the raymarine equivalent of the gfs10 if there is one, or put a garmin gmi10 or gmi20 in your boat to operate the gfs10.

Use a Floscan

For this I would agree with CME. A Flowscan would fit the bill.

A flowscan sensor or standalone monitoring unit? I like the idea of the gfs 10 because it looks as if I can be up and running for around $200. Are their any specific floscan units you are referring to?

You are in a hole. There is no easy answer. Either pony up for a maretron system, lowrance system, garmin system, or digital Floscan system. All of your options are extremely unpleasant, financially.

Your last option is a simple analog Flo Scan system. Or hook up your motors.......

Good luck with your decision.

Additionally, that A70D was abysmal at flow data retention and only the newer Raymarine plotters have all that any new plotter has, and more. So the reason for Raymarines lack of help is that your plotter was discontinued many many moons ago and Raymarine does not, nor had they ever with that unit, had software to manipulate the digital required input fuel data.

One potentially awkward solution is to borrow a Garmin MFD from a friend, connect it to your NMEA2000 network (and 12V power), and use it to calibrate your GFS-10. You'd have to go through that process again if you wanted to change the GFS-10 calibration for whatever reason.
