Hi,
I got a Yanmar engine (3YM30). I only have an "overheating" signal
but would like to get a temperature gauge installed. I have a C-80
Raymarine on my boat with supposedly can display temperature data when
transmitted in NMEA-2000 format. So it should theoretically be possible
to display engine data on my C-80. The trick I suppose would be to
somehow convert the analog temperature gauge data into a digital signal
and encode in NMEA 2000.. so my question is this:

1) Do you know of anybody who makes such a device?
2) Any generic parts that could be coaxed to do this?
3) Installing an analog gauge would be a lot easier?

Thanks
Ax
