Does anyone have an opinion about removing the spark plugs in a 3.0LX mercruiser after you have fogged and stalled the engine. Removing the sparkplugs and squirting a little oil down in the cylinders? Then replacing the sparkplugs. It seems that I read this some where and I did it, but now I don't see where anyone says to do it. I hope I won't have somekind of problem in the spring. Any opinions are appreciated.
