Hey fdheld34,

As an after thought, I thought I would say that in boating GPH iis more common a value than MPG, as in automobiles. It lets us set trim tabs, balance and the like to attain the most efficient setting possible for current conditions which are constantly changing.

In addition to managing efficiency and fuel consumption, I believe the most VALUABLE aspect of a fuel flow gage is that it frequently allows us to pick up on general engine performance and detect small changes in our engine's general health more quickly so that we can begin to be aware of changes in general engine performance from such things and water in fuel, dirty/clogged fuel filters, poor spark plug performance, etc. Some of these things will only be evident when major break downs and the like occur and they are usually more expensive than throwing a new or regapped set of plugs in, changing a fuel filter/water filter in the fuel line,etc.

As I said,just a couple of after thoughts. Again, good luck!
