Congrats! I know the feeling,it took me 3 yrs of badgering to get the owner to sell.You'll get lots of good info from the people on this site.

As mentioned,are you sure it's a Bravo2 drive? or is it a Bravo 3 with dual props.The Bravo 2 drives are not commonly used unless it's on a heavy work boat or big loaded hulls.
I don't know about the fuel burn on the Bravos,but depending on water conditions, my 350 260hp Alpha drive in my 74 23' Tsunami burns between 10 to 13 gallons per hour at a cruise speed of about 25 mph and 3200-3300 rpms,and at around 3000 rpms,I'm around 8-9 GPH.

At a wide open speed of about 36 mph It can suck down 20-25 GPH(and even more in snotty water and wind).
At a troll of about 3mph,surface speed,or 3-4.5 mph GPS depending on currents,I'm at about 1.2 to 1.5 Gph.

One thing against me is that on top of it being a cuddy model, I have a lot of canvas and isinglass work that extends up another two feet above the windshield.It is basically a big wind catcher and without a doubt,affects the fuel burn.
