How to Stabilize Fuel with Mercury Pro Seth Feider

Don’t forget this simple step in the boat winterization process

On the Water Gear & Tech How-To

Success at the professional ranks of competitive fishing often comes down to mastering the variables that can be controlled and managing the ones that can’t.

Those variables range outside of the usual things you’d expect to have influence a fishing tournament – like the weather and seasonal patterns – to include things like fuel quality. Poor-quality gas and ethanol blends can lead to issues with a boat’s fuel system, yet they’re often the only options available near remote fisheries.

Thankfully, even though fuel quality can’t always be controlled, it can certainly be managed with the Mercury Fuel Care System. The system includes three additives:

  • Quickare® Fuel Treatment can be added at every fill-up to help maximize engine performance.
  • Quickleen® Engine & Fuel System Cleaner is designed to be used intermittently throughout the season. It helps optimize fuel and remove harmful deposits.
  • Quickstor® Fuel Stabilizer is for long-term and offseason storage. It helps prevent the fuel from breaking down and can help keep the fuel system clean for a full year.

Why Stabilize Fuel

Quickstor is especially important for anglers and boaters who live in the home region of Mercury Pro Team member Seth Feider. A Minnesotan, Feider launched his career up north, where fishing seasons are short and storage seasons are, unfortunately, all too long. He knows that gas left in an idle boat can lead to fuel-related problems down the road if preventive measures aren’t taken.

The fact is, no matter the initial quality, all gas starts to break down after several months. The longer it is left in a boat, the greater the chance of it causing problems, such as hard starting, gumming or varnish formation in the fuel system.

When to Stabilize Fuel

Keep in mind that stabilizing fuel isn’t limited only to winter prep – and it’s certainly not limited to anglers. It’s a smart move to stabilize fuel in any boat that might sit for more than a few weeks, like a boat stored at a summer cabin or a family boat that is used only on occasion. Regardless of the circumstances, Quickstor has you covered. It works with any brand and type of gasoline-powered marine engine, whether carbureted or fuel injected. It can even be used in lawnmowers, ATVs and other small engines before storage.

So, when you are ready to winterize – or if you’re just putting the boat up for a spell – watch the included video for Feider’s advice. Then follow these steps to get the job done right.

How to Treat Fuel with Quickstor Fuel Stabilizer

  1. If you have old gas in your boat, run your tank as close to empty as you can get it or pump the fuel into your tow vehicle. If you have new gas in your tank, you can skip this step.
  2. Add Quickstor to the fuel tank. It’s ideal to add it before you refill the tank so the new gas will thoroughly mix with the stabilizer. It only takes 1 ounce for every 5 gallons of gas. If you put in a little too much, that’s OK.
  3. If you can find ethanol-free gas in your area, use it to refill your boat’s tank. That alone can prevent a lot of problems. Otherwise, buy gas from a trusted source that you know is getting new fuel on a regular basis. For most late model boats, fill the tank to the very top to prevent condensation from forming in the tank. In an older boat with a vented fuel tank, it’s recommended to only fill the tank about 95% full. Otherwise, extreme low temperatures can cause the fuel in a full tank to expand and spill out the vents.
  4. Back the boat into the water or fit engine muffs over the cooling water intake (see your engine owner’s manual for instructions) and connect to a garden hose to maintain a flow of cooling water through your engine. Then start the engine and let it idle for 5 to 10 minutes to distribute the stabilizer throughout the fuel system.

Winterization Matters

Quickstor should be a part of the winterization process for any marine engine. Also be sure to replace the fuel filter and, if servicing a four-stroke engine, to change the oil and oil filter. Then follow any other winterization procedures recommended in your engine owner’s manual before putting the boat up for the season. If you’re not interested in DIY, a Mercury Authorized Dealer can help you out, too.

Proper fuel care during boating season and ahead of storage will make sure your engine will be ready to go next spring, whether you plan to chase fishing’s biggest titles, like Feider, or you simply want to enjoy more fun and adventure on your local waters.
