Review: Winter outboard storage must have! - Great item. I always use this at the end of boating season to ensure easy start ups the following spring. It has worked great for me and saved me money in costly carb rebuilds after the winter months.
Review: Works Great - I use this every winter when I put my boat away for the winter. I have pontoon with Mercury 350 hp. The gas tank is like 47 gallons I think. I fill up the gas on my final outing of the boat season . Then I put the entire bottle contents in the gas tank. Let the boat run 10 minutes or so. I’m good to go until spring. I’ve never had a fuel related issue using this stuff.
