Not an outboard guy but I fog out my mercruiser at the same time I run antifreeze through it. I use either some fogging spray or slowly pour in some mystery oil.
Forgot to mention this motor is permanently attached to the boat as its a side console setup. I don't plan on removing it from the boat. Also, the garage its being stored in is heated. Does this change anything?
