Location: With my son on the water | I maybe should start another thread but this is still about gas.
A few years ago I had an idle issue on my merc 150 four stroke in the late fall. The motor would shake more than normal at low idle. I noticed it right before I put the boat away.
So I stored the boat and winterized as normal. Fogging the cylinders. Then in the winter I call the mercury technical hot line and got great help. The guy thought I was getting carbon from either trolling, low speed running due to being cold, or both.
He told me to run Merc Quickleen in my first tank in the spring to clean up the carbon. So I did that and it ran great.
He also told me to use Mercury Quickcare with every fill up as it has both a stabilizer and a cleaner. He then said right before winterizing to run Mercury Quickstor as it has stronger stabilizing agents and fog the cylinders when I store.
Obviously repeat the process year after year which I have been doing for about 4 years with zero issues.
Like Steve said a bottle will treat like 60 gallons and cost around $10 a bottle.
