Raymarine E120 Classic, fuel %'s all over the place.

[jaywoodz]

I have a NMEA 2000 network tied in with my Raymarine e120 classic. I have a Mercruiser N2K gateway that takes smartcraft and turns it into NMEA 2000. I have a smartcraft sensor tied into my engine(s) that reads both my port and starboard tank %'s. As in percent full. I've attached a picture. Problem is.. even in the slip, not in gear, low wind and very little rocking on the boat, my tank percentages jump around SO much. For instance, I watched them for about a minute. Each tank jumped anywhere from 17% to 40% full. Just sitting there! It's terrible, and almost worse than analog that control the spiking. Is there anything I can do to get these to stop jumping around so much? It's terrible and I can't get an accurate reading for my tanks.

If you have the factory swing-arm fuel senders in the tank you could try replacing them with the sliding pick style such as those from Royce Industries. I did that on my 300DA and it significantly reduced the bouncing of the levels.

That would be a great start. Can you provide a link ?

Here you go. My 300DA had 85 gallon tanks which took the 20" length.

Thanks for the link. About how much did those run you? I also just requested a quote. Hopefully, if cheap enough, that will solve my problem.

$83 each when I bought two years ago.

Can't this be read from the computer on the engine?

Yes, that's how I'm getting the information to the MFD. Engines are hooked into my NMEA2000 network.
