I have a new merc 50 4 stroke and was looking at fogging it but one of the cylinders I can not hardly get to the spark plug. I have heard from some others that it isn’t necssary to fog it. I have heard to only change the lower unit oil and engine oil put in sea foam and thats it. Some say that the fogging oil hurts the engine. Wondering what to do. Thanks
will shoop
