I was out again today, every thing's running smooth, looks like I am going to be getting between 7-8 GPH at 3600 RPM and 26 MPH. That is also including runnig the 15 HP Honda kicker for about 6 hours each day. So, maybe I am closer to 7gph. I was hoping for a little better but that is really better than the old Merc 200 carbed engine.
People want too much $$$ for fuel flow guages, I could have gone for Honda digital guages w/it for addition $850. That is pretty expensive to how much gas you are burning. It doesn't feel so bad now that gas is back down to $3.37.9 here.

Thats more than double the MPG of my 20MA. I have a NavMan 210 fuel moniter. It'll give GPH, fuel used, or fuel left. $125 @ Bethel-marine.com . I've decided I need a backup for troublesome fuel gauges.

TARPUN, How much of a job is it to install one of the F210s?
Are they accurare?

Gary, It's an easy install. 2" hole in dash, the fuel flow transducer goes inline in your fuel line after your fuel filter (between filter and engine) in an upright position. Hook up pos. & neg to your 12 volt system and you're good to go. The toughest part is the hole in the dash.

It seems to be pretty accurate but I really don't have a lot of time on it. I would say it's within their claimed accuracy of 5%. It is supposed to able to be calibrated by the user to within 2%.

Thank you for the quick response. I already have a vacant hole plugged in the dash from the old instruments. My Honda/Racor filter is in the motor well, so that would leave wires exposed, how did you deal with that?

My fuel filter is mounted on the transom inside of the access door beneath the starbord side stern cooler/baitbox. The fuel transducer mounts next to it. On my application I just fed the cable under the deck back to the console. The transducer cable is the only wire that needs to leave the console and it's about the size of maybe #10 wire. You could bundle it with your motor harness or at least feed it thru the same access.
