Milky liquid on top of drive shaft

[BC20xd]

I have a 99 225 Promax 0g857204 that I replaced the gasket on the two piece exhaust his weekend. When I pulled the lower unit off the top of drive shaft was milky looking.I also had some on the top of exhaust plate where the dive shaft goes through. Is this anything to be worried about? I replaced the two crankshaft seals in the fall. Thanks Billy

Did you clean up up the oil that had leaked?

Yes. its running fine and compression is pretty much even at 147lb. I had the head cut down some a few months ago. Thanks

If you cleaned up all of that oil when the seals were replaced last fall, it sounds like you (again) have a leak.
