Hi there,

Does anyone know if there is such a thing available as a fuel computer for a boat?

I found one on e-Bay, but it was in the style of the 1950's and not quite what I want!

If you know of a GPS Plotter that would accept a fuel flow input to give a MPG reading even better (although plotter budget is a couple of hundred quid not thousands...)

No, not bought a boat yet, but some of the ones I am looking at have very large engines and finding the most economical speed will be of much benefit....
