I don't have one, but a Navman 3100 fuel moniter and 2nd transducer would be in order to get the best fuel milage.

About 1.5 mpg at cruise with twin 150 carbed yammies. Can get 1.8-2 in ideal conditions with a moderate load.

Figure with 200s, at least with my '90 Yams, you're burning 20gph @ 4000 RPM. While off plane, you get under 1mpg, it gets better as you increase speed, 3800-4000 is about most economical on my rig, I'm getting 1.5 nmpg at 4000
