Is this normal?

Usually, my 15HP 2-stroke Yamaha spends the winter lying on its back (tiller arm up) on the garage floor.
This year, I decided to use a dolly to store it upright instead. I have it strapped to the dolly (with foam insulation where frame meets frame) and built a sort of platform so that the dolly is tip-proof.
When I went down to lock up tonight...I noticed a big puddle of black goo on the floor at the prop-end. I'm hoping this is just the "winterizing oil" that i poured into the spark plug holes, that found its way down the leg and out the exhaust ports.
Does this sound plausible, or am I looking at some major repairs next Spring?
I haven't actually checked the goo to see what it is...I've got to go to sleep now because I work early tomorrow. But the black puddle has me "concerned"...

What do you think?
