Interesting, I have a couple small airports not far and can ask them. I
remember they had the aviation fuel which was higher octain to prevent
carb freeze ups on the older planes.

I remember also they sold the fuel from Esso in the 45gal drum. I think
there is a wholesaler like that near also who sells by the barrell and
is knowledgable about our local fuel content and should ask those guys.
Maybe they will sell me a drum or two of exactly what I should be using
because that is all I really use in a season and it would be easier to
fuel it that way. Maybe cheaper. thnx for the ideas

Hi

Anyone comment on the alcohol in today's fuels? It seems there are
very much
fewer stations around supplying fuel without the alcohol.

Is this alcohol causing problems with any components in the system?
Eating
the neoprene or rubbers? How about the fitch injectors on the
evinrudes. The
manual specifically states not to use the alcohol in the fuel but I
cannot
find where to buy the fuel without alcohol. Some locals are talking
about a
blue enzyme to put in. Some are taling about lead additives. Anyone
have any
comments? Should I be worried?

Still running some gunk through the 9.9, thanks for all the advice
and tips.
No real improvements yet so might have to take off the carb as Wilbur
has
suggested. Thanks again all for any great advice.


From all I read, nearly all "gasoline" sold in the U.S. contains an
"oxidizer" and likely some alcohol. When the first reports about
gasohol, gasoline/alcohol mixes was publicized it was stated that some
fuel systems contained seals that were not compatible with the new
gas/alchy mixes. In other words, the new fuel might eat the seals out
of your carb but wouldn't make the piston rings explode.

If you want "pure" gasoline go down to any airport that supports light
airplanes, you know, Piper cubs, Taylorcraft, home builts, and others
of the same ilk. They sell straight, old time, gasoline fuel.





My experience is only anecdotal, but I ran gasoline out of the gas
station pump for nearly 20 years in a variety of Mercury and Yamaha
outboards, two strokes and four strokes, and *never* had a fuel-related
problem, even though the "deadly ethanol" was a component of the fuel
for those years. I also run gas station pump fuel in my lawn tractor,
lawn mower, chain saw and string trimmer, and don't have fuel-related
problems with those devices, either.

Certainly. The warnings that I have read all stated that alcohol
containing fuel MAY cause problems. A few years ago when gasohol
became commonly available in Thailand the Bangkok Post newspaper
contacted the various car manufacturers who sell cars in Thailand with
the question, "Is it safe to use gasohol in your cars". Most of the
manufacturer's responses was a bit like, "All our cars since 1985", or
some such.

Apparently the warning is much like many of the safety features we see
today. If it is at all possible then warn against it.

I think it depends partly on the climate. I rarely had fuel issues
when we were living in the northeast but here is south Florida
carburetor issues are rampant on all kinds of engines unless they are
frequently used or run completely out of fuel before sitting idle.
The newer 4 stroke marine engines seem particularly vulnerable,
perhaps because of smaller carburetor passages as one mechanic
explained it to me.



Two of my Yamahas were four strokes. Both had external, as well as
internal, fuel filters. Perhaps that helped. My lawn tractor, with a two
cylinder Kawasaki engine, sometimes sits over the winter with a few
gallons of gas in it. In the spring, it starts right up, as soon as I
top off the battery. The two cycle tools usually go through the winter
with dry tanks. I know plenty of folks have had problems with ethanol
fuel but, knock on plastic, so far I haven't.


I can only say that you are lucky. In fact the most common repair for
outboard motors here, that have sat for a while without being run, is
"change the gasoline" And it nearly always does cure the problem.
