I have a pontoon with a 300HP Mercury Verado hanging off the back. I am getting ready to do some spring maintenance (oil, gear, impeller, etc..). I keep the boat on a covered lift. It never sits more than 3 months in the winter without running. Is that short enough of a time to not worry about fogging the cyclinders? Should I be fogging them in October? Open to opinions. I ran Stabils marine stabilzer in fuel tank in October. I usually get a few nice days through winter to get on the water, maybe 2 to 3 times.
