[C320-list] Black Oil in Mixing Elbow

[Jon Vez]

Kevin,

Did you check the area where the hose connects to the mixing elbow? I've had
to regularly tighten mine to prevent leakage. The exhaust water typically
creates a telltale drip line that runs down the hose and onto the
transmission.

I noticed a black oily substance dripping from the mixing elbow. From under
the elbow itself. It appears to be motor oil, but not sure.
This Yanmar 3GM30F with 180 hours, runs great, no missing, shaking etc. No
loss of engine oil, just a mess as it is dripping onto the transmission
case and to the starboard side of engine compartment. Any idea what this
could be? The yard mechanic is mystified too.

Thanks all.

Kevin
