A Quick Tip
Be sure to check your grill's gas tank prior to starting to grill the turkey. A full tank usually lasts about 17 or 18 hours, so make sure you still have enough left to completely cook the turkey.
Use Your Grill
The following is a guide to how long to grill your turkey based on its size: 10 to 11 lbs. = 1-3/4 to 2-1/2 hours, 15 to 17 lbs. = 2-3/4 to 3-3/4 hours, 22 to 24 lbs. = 4 to 4-1/2 hours.
