Fuel Flow Meter/Gauge Questions

[stoney]

I have navman F3100 and i can not recommend them. It was very useful for 2 years and now the display has faded out. I contacted navman and they will not warranty it but will sell me another display for $200. They also got a bad batch of senders and had to replace that. Now I have this 4" square hole in the dashboard that is useless. I upgraded to a new chartplotter and will add the sender compatible with my chartplotter this winter. I found it very useful to see mpg.

That sucks. I had the exact opposite experience with NAVMAN. I had a fish finder out of warranty go bad and they replaced it with a new one for $99 repair fee. Sent a new transducer to boot. How long ago was that Stoney, I have only had excellent customer svc from them

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!
