I never checked what kind of fuel milage my twin small block 28 got but I would think 2 mpg would not be out of line... Like anything else just depends on the right hand.. Sounds like you are going to have a real nice ride !!

I rarely saw better than 1mpg with my single 525SC. Then again, I rarely saw anything under 5,000 rpms either!

Austin, that's a "cool" smiley... i agree w/ 2mpgs.

With my 560hp cruising at 4000rpm(50mph), i was at 2mpg.

I was pretty suprised with the fuel consumption on the 28, albeit not a pantera. It wasn't that much different then my 24 python with a single 502. All in all I probobly burned an extra 25 gallons on a normal weekend over the single engine boat. I only needed 2800-3500 rpm compared to the 4000-5000 rpm on the single.

I'm thinking about going with a Merc system view gage... gives you all that info. If you crusing long distances it would help to know the most effeient cruise. I guess you could also do it the old fashion way... fill the tank, ride a certain distance, then fill up again- for MPG.

I would like to have a fuel flow meter myself to have a better idea of the most efficiant crusing speed... But then again I need to actually have my boat running first....

some fuel flow meters cant keep up w/ big hp flow.
plus you may need to take dramamine while watching it.

Tom, austin hit it on the head... fill up, run a good ways at a consistent cruise, then fill again. Then use your 6th grade math.

Yeah thats great for the guys on here who can actually afford to fill up there tanks 2 times in one year....lol...

Wasn't sure how good the meters actually worked. They are kinda pricey anyways if I remember & that being the case it would be like the people who go out & spend several thousand dollars on an econamy car to save money in fuel...
Just thought one would be pretty cool to have if they actually worked.
