225 EFI throttle body leak

[wjhuskey]

I've had a leak seaping out from below the cowling and down onto the upper gearcase housing of my 1998 225 EFI serial number 0G68-2033. Underneath the cowling looks mostly clean compared to the slightly larger amount that leaked onto my garage but today I did see signs of leaks around the back of the throttle body. I've got a pic of the throttle body and pics of the leak. Advice? Thanks in advance.

Most likely split recirc line

UPDATE: took the boat out on a short run this morning and there was no oil/gas on the motor afterwards. All the old was gone and no new leakage - lower unit was clean. No new leakage under the hood either. Oil levels in reservoirs fine. I had been running it on muffs the past few months just to keep it loosened up while setting in the garage until I had time to get it to the lake. Maybe it just needed to be ran on the water?
