Pull the prop shaft bearing carrier. 2 o-rings around the carrier, 2 seals on the prop shaft and the small seals under the heads of the 4 bolts. While you are at it, change the zinc

Could also be unburnt fuel/oil, are you positive it's gear oil?

zinc should be bolted to the bearing carrier, between the two "flange" sections. its a half-round piece
