Hey folks, how many miles or gph do you think you're getting out of your tanks? Assuming:

1. You aren't full throttle all day
2. Haven't done all the mods to seal the jet pump from cavitation
3. Bimini down.

Just curious. Thanks all.
 
I would take a guess but I have done mods and almost always run with the bimini up. It's less then 100 miles for sure. The display will tell you a rough gpm guess based on injector pules so you could look at that
 
Divide your speed by the gph to get an instantaneous mpg figure, this is a great way to find your best cruise speed / mpg.

You can always reset the fuel used page and get the overall average mpg, total mikes traveled and total fuel used.

Lots of other things factor into it as well, wind, waves and especially how much load you have in the boat.

If you have the normally aspirated 1.8L engine and are not heavily loaded I’d guess your mpg to be around 4 at best cruise.
