New poster with a "newbie-type" question.
The specifics: 1948 Gray Marine Phantom Six - 104 engine. Restored several years ago but installed recently in a restored 1948 Resorter. Total run hours thus far, about 6-8. Engine runs well.
The situation: Shortly after running the boat, all the tops of the spark plugs developed a white surface "corrosion" (The plugs are Champion UD16). I have attached two pictures. What is this corrosion? Is it normal? Can it be removed or prevented? The engine is located in an enclosed engine box, but I believe there is adequate ventilation.
Thoughts?
Thanks,
Mike
