Florida had owned the series recently, winning the past four meetings and seven of the past eight games against the Bulldogs overall. However, the Gators couldn't overcome a cold stretch in the second half.
Florida endured a four-minute scoring drought late in the second half. Koulechov hit a pair of free throws with 5:18 to play, and the Gators didn't score again until Keith Stone hit a 3-pointer that trimmed Georgia's lead to 66-56 with 1:09 to play.
Koulechov knocked down a 3-pointer that gave Florida a 20-16 lead midway through the first half.
Tyree Crump ignited a Georgia spurt with a pair of 3-pointers, and the Bulldogs closed out the half with a 19-8 run to take a 32-27 lead into halftime. William Jackson had 10 points in the first half to lead the Bulldogs.
Florida opened the second half with a 12-2 run to regain the lead. Jalen Hudson sank a 3-pointer, and KeVaughn Allen had a dunk in the Gators' quick start.
Georgia battled back and was up 55-51 after a three-point play by Maten with seven minutes left.
Jackson finished with 16 points, and Juwan Parker added 10 points for the Bulldogs (13-8, 4-5 SEC).
Georgia hit 12 consecutive free throws down the stretch to seal the win.
Florida returns home for two SEC games, beginning with a visit from Alabama on Saturday.
Three of Georgia's next four games are on the road, starting at Mississippi State on Saturday.
