I went back through the manual and didn't see anything about fogging through the spark plug holes.
I was told this a long time ago by my buddy who has been a Nautique dealer for over 25 years. Something about an oily residue can build up over the years if you continue to fog a dry intake. I would also think getting fogging oil on any sensors like the MAP sensor would not be a good thing either.
