What can I do to protect myself from the potentially damaging effects of ethanol?
Fortunately, there are simple procedures that can help, but it's important that you do your part.
This is one part of maintenance you must proactively do for yourself. As you read, scan the

• Install a 10-micron fuel/water separating filter
your outboard. It filters the gas and allows any water (which is heavier than gas) to safely
sink to the bottom of the filter and out of the fuel. Yamaha's spin-on 10-micron filter traps
impurities down to 10 microns in size (1/20th of the diameter of a human hair), to keep your
fuel clean, and has an extra-large water-retention area. And since it's
a spin-on, it's very easy to replace.
Tip: Carefully filling a new replacement filter about
¾ full with fresh, stabilized fuel before installation
will make priming the fuel system afterward much quicker and easier.
Tip: Apply a thin film of clean engine oil to the gasket when installing the filter.
That will make it much easier to remove when it's time.

Add fuel stabilizer and conditioner to every tank of fuel.
•
marine-specific non-alcohol-based formula, like Yamalube
PLUS. These formulations are specifically designed to work effectively in the moisture-rich
environments common to boats. And don't believe some of the claims you
see today; no matter what you add to bad gas, it's still bad gas. No additive
will restore stale fuel, remove water, or cure ethanol-related issues.
Tip:
Today's gasoline can begin to break down in a matter of weeks, not months. Make sure to treat
every tank of fuel, not just for extended storage. It's cheap protection against a world of hurt.

Add Ring Free PLUS internal engine cleaner to every tank of fuel.
•
The cleansing additives in the majority of today's gas are a great
start, but they're formulated for automobiles, so they may not work
as well on your outboard. Do them one better. Ring Free PLUS
makes performance-robbing carbon chemically unable to stick to
internal engine components. The "PLUS" is a proprietary blend of
synthetic anti-corrosion additives that helps protect the "yellow
metals" in your fuel system (copper, brass and silver solder) from
corrosion. These are key components to proper fuel system
operation. This helps maintain their performance and reliability.
Ring Free PLUS also cleans gums and deposits off of internal engine
and fuel system components.

• Buy your gas where they sell a lot of it.
The goal is to keep your boat's fuel fresh and potent
at all times. Why buy gas that's already been sitting
around untreated? Buy the freshest fuel you can find,
and at fill up, treat each tank with Yamalube Fuel
Stabilizer & Conditioner PLUS and Ring Free PLUS.
Add these before adding the fuel so they mix up well.
It's an easy, proactive and protective habit to get into.
