I have a Lowrance LMF200 with a paddle wheel speed sensor and a fuel flow probe. It displays MPG (and all kinds of other parameters) in real time. I replaced my gas gauge with it at my helm as it's also an incredibly accurate (within 1%) gas gauge. It will connect to a GPS with NMEA2000 outputs for very accurate speed readings.
I've discovered that my best cruising speed is around 32 MPH, but that I get nearly the same gas mileage between 28 and 40 MPH.

I've been thinking of adding something to my Garmin 440, but can't seem to find any info on their site. My unit can be used with a transducer, which would show depth and water temp. But I can never seem to find any info where I can hook it up to the mercruiser engine, which is fully smartcraft enabled as well.
