Reply To: Gearcase leak…where? how?

In my first post, second photo: Yes….the light green stuff (center & left containers) is the oil I drained from the gear case. By contrast, the container on the right (dark green) is a sample of new oil from the same container that was used to fill the gear case in the spring.

The sludgy stuff up around the impeller housing is fuel-oil residue? Very interesting. If I can rule that out, then this may be as simple as plug washers.
