What tpye of electronics do you have?? I have the LMF-200 Multi-Function Gauge from Lowrance but there is a catch. I put the first one on in 05 when I got the boat and have replaced it twice under warranty, the third time in August.
I have a X-15MT plotter that does not support the newer LowranceNet so my fuel flow was suported by a paddle wheel for speed input giving me miles per gallon.
In Aug the one they sent was a 2009 unit that ONLY gets speed from a newer paddle wheel or the network. So now have no speed input but it does still give me all the info on fuel used, gallons per hour etc.
My point is the LMF-200 is a multifuntction gauge that does much more than my X-15MT plotter can support.
It is depressing to see that my 1989 225hp Johnson is burning 13.5 to 15 gallons per hour making 24 to 27 knots!
