I just got the GFS10 from Garmin to integrate with my GPS440S and absolutely love it.

same thing with the lowrance unit you get the ep10 fuel sender and the small guage then if you upgrade to a bigger gps unit it will work on that.

my cuddy had a 175 yamaha got 2 1/2 mpg at about 4500 rpm, 60 gal gas = 150 miles
Remeber the rule 1/3 to go 1/3 to come back and 1/3 for reserve and you will be fine.

If you go 100 miles will you have a gas statioin some were along the line??

Thanks ALL for the info.
I get around 2mpg on my 8 mile trip to Icaco Island, 4 miles @ 7knots going in ( upwind ), 22knots coming back ( downwind ).
I have an idea. I will pull a digital fish weighting scale I have somewhere, and do some calculations measuring the weight of the fuel used ( I`m using portable tanks ). That wil give me a fairly exact fuel usage using the weight of one gal of fuel/oil, and combine that to the average speed on that leg from the GPS. I will post the findings.

***I can guess that 2mpg is the rough magic number here.

THANKS FOR THE INFO AGAIN COMRADES.

I suggest one of these. This simple addition will improve your mpg to 5!

YESSSSSS !!!
I want one of those !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
In my case it will pay for itself in fuel savings, but I need to come up with the "maryjanes"
( slang for $$$ ) in my area.
If I get to sell my Yami, I will be in the dealer next second.
