spatchcocked turkey - 9.75 pounds - how long to cook? :)

Woogeroo

Hiya folks. [p]I have a 9.75 pound turkey that I spatchcocked(cut out the back bone) and have on my old style big green egg. I have it cooking between 225-250 F dome temperature. The turkey has not been brined... at least by me. [p]So, any guesses on when it may be done? The natives hereabouts act like I am some kind of expert and I should know EXACTLY when it should be done or something. My attitude is that they should learn how to smoke luscious and yummy birds... but that would require too much effort on their part. He he he. [p]So the details: [p]9.75 pounds
225-250 F dome temp
not brined.
spatchcocked(back bone cut out)
cooking what was inside, face down on the grill(on a rack - for ease of removal)[p]So... thanks folks.[p]Happy Thanksgiving. [p];) [p]-W
