Green gear oil in bilge, where does it come from?

[liquidlew]

Found a small puddle of green gear lube in the bilge right under the motor/oil pan. Cleaned it up and I can see it's dripping from just behind the engine. Tried to get a mirror up in there but just can't see it. I know gear oil goes in the bottom of lower unit and I thought it stops up at the oil vent hole. Does it go into something thru the transom into the engine area? I checked drive oil level and had to add maybe a half cup. Oil in drive and in puddle is clean, no water. What is leaking and I suppose I gotta pull the drive (or more) to get to it?

probably coming thru the ujoint bellows from the seal next to the ujoints in the upper gear case.
