Carbon

[<Orvell4>]

When I closed in my boat I noticed a lot of fine carbon all over the deck of the boat. I don't know why my ehaust has all this carbon in it. It's a 98' mercury XL150 and runs great. I do run quickleen in my gas, could this cause my problem, or is something serious about to happen?

Burnt oil = carbon...

It's better in the exhaust than being left in the motor itself...

Why are you running quickleen?????
