1970 40hp Johnson

[boater10]

Hello All:<br />Stored this motor in the basement over the winter. Hooked it up the other day and ran it just with the muffs on. Started up no problems. After I shut it off, I noticed a greyish fluid coming out the exhaust outlet. Is this a minor or major problem. All info is greatly appreciated. Thanks<br />Steve<br />Nova Scotia, Canada

Not any kind of problem, boater.<br /><br />Normal residue from incomplete combustion.

Thanks alot JB. Wasn't sure if anything should becoming out of exhaust besides fumes. So this isn't a sign of bad gaskets or anything. Going to sell boat and want to tell the buyer as much as I know. <br />Steve

Boater, that's so normal it hurts. It may even be black, it's just exhaust residue. My 28 is guilty of it, especially after prolonged idling in cold water.
