what is this?

[kb3gup]

Hello,

I noticed when running my engine on muffs there is a decent amount of black oil coming from behind the prop, it forms a puddle on the ground when the engine gets shut off. Is this normal and what is it? I used 2 cans of OMC engine tuner this year so I doubt its carbon, unless it's just what was built up that got dissolved and is now running out.

Also can I mix the XD 25 oil (old XD 30 I'm told) with XD 50 oil?

Thanks!!

Its just unburnt fuel, oil and gunk mixing in with the water. Its kinda milky aint it? Its normal. It'll drip for a bit after you run it.
