MPG chart.
 

Put it on a chart to be able to see what the best range would be, all I got to do is remember to take it in the boat.

Hi tsubaki
I know this is an old thread...but it looks like you most efficient "cruising speed" is ~ 35-37 mph at 3 gph with the 150hp engine?

Did you prove this out? That is pretty efficient for a 2 st!

Thx, bill

That would translate to 12 mpg. Give the V20 a range of 600 miles. Sign me up.

Those were simply range numbers if you had a fuel consumption gauge and was able to maintain a given speed while drawing a certain amount of fuel.

"IF" you could maintain sucking only 3gph at 37mph you would be getting 12.3mpg, multiply that by your available fuel then you would come up with your distance able to travel.

This is probably the thread that got me to do the graph or vice versa.

The actuality of it is, how it always was.
The faster you can go while consuming the least amount of fuel, the farther you can go.

The gph gauge was very important to me since I have only 2/20 gallon saddle tanks.
If I was fishing offshore and I was pressed for time to get back without running out of fuel I could calculate my available range by the gph/mph chart.

Our dock is 15 miles from the sound and around here we need to run another 6 miles to the first offshore reef which is in only 30' of water.
The next nearest reef is 10 miles offshore but it's in only 40' of water.
To get into some decent fish we need to be about 25 miles offshore and at that it's only 55' deep.

So you figure if I was wanting to fish 25 miles offshore and if I was able to maintain 30mph at 11.06gph (2.71mpg) I could go 108 miles on 40 gallons of fuel. The actual trip would be 80 miles and consume 30 gallons of fuel.

See why I was so worried about the fuel consumption?

Oh yes...i do understand. For those of us that fish offshore range (- gph) is critical!

I was wondering if you have had the chance to prove your extrapolations.

And what was your baseline?

Thanks, Bill

:head::head::head:

so MPH divided by GPH= the values in Miles per Gallon

IF you are travelling 1 mph @ 1gph you will travel 1 mile using 1 gallon in one hour

The chart doesn't do anything for you if you don't already know you gph rate at any given mph.

If you know your gph at a given speed you can use the chart to calculate range at a given speed.(if you accurately know how much gas you have)

If you accurately know your gph, you probably have a electronics telling you your range.

Just wished we had water that deep at those distances. 20 miles gets you 25 feet of depth, 40 miles gets you mid 50-55 feet deep. Gotta head out around 65+ to get around 100 feet.

take a road trip to Pompano Beach. 15 miles>1000ft ... Boat a sword on a V20:sly:
