70 gallons, 8.2 liter 425 hp Cobalt. Can burn that up in anywhere from 3 to 8 hours running time.

I carry 2 six gallon portables @ 5mpg, not too bad.

My tank is 96 gallons, feeding a Mercruiser 496 Mag HO. I'm not sure how much running time that gives me since so much depends on how fast I'm cruising and how much I get into the throttle, plus how much weight I'm carrying on any given day. I usually cruise at 45mph, sometimes 50, but with the price of gas now, only occasionally do I go wide open throttle. Since I trailer, I'm lucky that I can fill up on land instead of at a marina; that saves alot of $$$! I usually fill up when it gets down to about half a tank so that means I'm usually filling up every third weekend that I use it.

We run 1 boat with a 120 gallon tank being sucked on by twin 300hp 350 Mags. Our other is a 38 gallon tank constantly being drained by a 225hp Optimax. I did not run the Monterey much last year but was constantly filling the toon as I drive it like I stole it...I am sure this summer will be the same, only more painful.

We have a runabout that holds 65 gallons and a small Whaler that holds two 6 gallon portables. I don't use the bigger boat much so I only fill it 3 or 4 times each summer, usually when it's still 1/2 full. I think we go through about a tank, sometimes two, per week in the Whaler, which isn't bad considering we use it to get just about everywhere that can be accessed via the lake (hardware & grocery etc) 7 days a week. The gas station is one of the few places we take the car during the summer and that is to fill up the portable boat tanks.
