[C320-list] Perkins Engine Leak - little help needed - Redux

[Warren Updike]

Thinking I should replace the 24 yr old coolant recovery hose, I went to 6 stores with no luck (2 marine, 1 hardware, 3 auto.) Found a source online (rockauto.com) but couldn't get before next planned cruise. Decided to cut ends from existing hose and reinstall with ss screw clamps. Ran engine to find water leaking from raw water pump. Cleaned mating edges of cover and installed new gasket I just happened to have on-hand. No more leak.
Unresolved: Why was overflow bottle empty? Why was I seeing what appeared to be coolant in the engine sump, maybe diluted with water from the pump?
Aah, the the joys of owning an aging sailboat.

Now, is my turn. Doing some light maintenance and noticed some fluid, maybe pint, collected in engine sump. It's light color, but has oily feel on fingers; and, has some dirt mixed in like it came from overflow bottle. Maybe coolant? I check heat-ex and it is full. Cap is new so don't suspect that. Check coolant overflow bottle and it is empty (always at "cool" line when cold.) Took bottle home and filled w/water left overnight...no leak. Hose connection from heat-ex seems tight with small screw clamp. No obvious coolant leaking on the engine or around the heat-ex.
How could coolant leak to sump with no obvious source?
