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.

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.

Use Regularly in my Optimax 150
I’ve always liked the Mercury family of fuel additives. I use them every time I fuel up to keep my 150 Optimax running strong. Quickstore keeps your fuel from breaking down during short or long term storage.

It works
I use this in non ethanol gas and it was stored 13 months this time. It’s a fresh when I used the gas as the day it was put in the container. I’ve used this product for several years and it always works great. The best stabilizer I have ever used.
