Got a quick question.. Has anyone ever tried calculating fuel Eco? Like a MPG on a cafe with out big power... I know it's a toy and some people don't care, I'm just talking about planning while out on the water if you go for a long run if you should plan on having money for more fuel type of situation..
I've heard a little less than $10 a minute but not sure. I don't think mines that bad but who knows.

So has anyone played around with trying to calculate this?

Pretty easy to do if you have a GPS. I haven't tried it yet but I'll probably do it for fun some day and see what I get.

running a poker run hard i use about 2 gallons a mile... but cruising isnt bad. just when you open up the 1150's they drink

The TRS drives will kill economy on your boat. I know they do on mine.

Could you elaborate on this? I've got a Garmin 540, and for the life of me can't figure out how far (miles) I've traveled. ...could be that my unit is to old to calculate, but not certain.

Thanks.

From the main menu click on "information". That will bring up a trip screen and a bunch of other stuff like max speed avg speed etc. you can reset all or just trip.

I'm sure it has nothing to do with a big azz heavy boat plowing thru the water ....LOL....

A big high performance twin cruising is usually 1 mpg+/-, and 2 gallons per mile running hard. That's a general rule of thumb for new and old high performance engines.

I have seen data for newer 8.2s showing 1.3-1.7 mpg cruising.

Now, a wet ride in a flat bottom heavy hull changes things of course.

My friend has a 24k lb 50 ft stepped vee with 3 1000hp that takes 3 gallons to each mile, cruising

Nope the 10,000 lb fiberglass tub is irrelevant. The trs drives rob all the power and burn the fuel. You would save tons of $$$ in fuel with bravos. Mainly because you'll miss a few weekends because of broken drives.

yeah but the Sandler is worth every penny!!! 100mph 50 footer
