Oil/Gas Leakage?

[puzle]

Last night when I docked I noticed a small thin amount of something on the water from behind the boat. It was not a lot and did not look like gas but did have a slight blue tint. I was at dusk so it was hard to tell.

I checked the motor location and all looks very clean. Does anyone have any ideas what this might be? I will be watching it more to see if I can figure this out.

That's normal.. the exhaust port is at the rear of boat.. you will sometimes see the exhaust smoke at rear of boat it will have oil/gas residual

Thanks for the quick reply. I had thought that might be it but as you can tell I'm a newbie boat owner.
