OK here is the specifics.
I have a Lowrance 330C
https://www.manualslib.com/manual/96...page=44#manual
It has the ability (pages 42, 43, 44) it seems to talk NMEA 2000.
I have a bang up to date Suzi 150DF engine with the standard SMIS gauge. It is NMEA 2000.
No one in the boat builder or chandlery community here in Lymington seem to know how to do this!!!
They suggest rather than trying to get the Suzi SMIS to talk to the Lowrance GPS receiver (LGC2000) {which is hard}, I buy a Suzuki receiver which is £400+....
All I want to do is to present real time fuel consumption on my SMIS gauge
Thx ever so
