Hello everyone. New to posting, but have been reading for a while. So much good information here. Thanks for all your help.
I just purchased this motor over the winter. Johnson JR15CRC 15hp. So far, it runs beautiful but am experiancing oil leaks at several points after running for a period of about a day. I have pointed out several points of leakage. Pic1 shows black oil leaking from the upper mount seals.

Pic2 (below) shows lighter oil draining from the inside of the lower power head cover.

As you can see I pulled the powerhead off not too long ago and cleaned out the lower pan and also replaced the main gasket and water pick up tube grommets, thinking maybe the leak was coming from the exaust housing alone. I found that the inside of the exaust housing was saturated with milky brown oil so it was evident that the darker oil was seeping out of the upper mount seals.

Could this leak be coming from the block somewhere? Possibly a common head gasket? It is really hard to tell since the whole power head becomes somewhat coated with oil after use.
Any ideas would be greatly appreciated. Thank you.
