Here in SC there's a LAW that requires alcohol/ ethanol pumps to be LABELED as such...are we the only ones??...

I dunno if it's law here or not, but in VA I've noticed those same labels at most the gas pumps I use.

We've got it in CT. It's on the pump and the attendants tell you about it if you ask. No problems with it so far. First i checked my tank construction (aluminum), then I ran last year's gas down as low as i felt comfortable, changed my fuel/water filter, added the new gas and have had not even a fart since (knock wood). 5.7L fuel injected Mercruiser.

NY pumps labelled "Contains 10% Ethanol".

From what I'm gatherin', alcohol doesn't have that negative an affect on motors, but on the fuel-lines, tanks and fittings it runs thru...once those things start breakin' down, small (and large) particles invade the motor and cause probs in injectors and carbs...is anybody else gettin' this same ''jist'' outta this?... ??? ...

Absolutely the same jist.

I still am confused as to why carbs and injectors in car engines can handle the
clean out crap better than boat engines.

And he// my lawn mowers would run on gas that has
mud in it (fecesioutious comment)

This from another post I have.

this what the clymer book says for Johnson & Evinrude, and it was published 1991, so they new it was coming!!

So I opened the repair manual to see how to adjust, and this is what I found

1.
Some gasolines sold for marine use now contain alcohol, although this fact may not be advertised. A mixtute of 10 % ethyl alcohol or ethanol and 90% unleaded gasoline is called gasohol. This is considered suitable for use in Johson and Evinrude outboards. Some gasolines, however, contain methyl alcohol or methanol. This is not recommended for 1973 to 1986 outboards and only under the provisions outlined under Proper Fuel Selection in this chapter for 1987 to 1990 models.

2.
If gasohol or a gasoline/methanol mixture (1987 to 1990 models) is used with any regularity, Johnson & Evinrude recommend that the carburetor jets be changed to provide a richer mixture to maintain good performance and pervent possible engin damage. See your dealer for recommended rejetting according to your needs.

heres a question for the experts...

I go out at least twice a week, and ever time I go I fill the tank. So I always have a full tank.
would it be better to run the tank almost empty to use up the fuel, or just continue to top it off each time?

MJ,
1991 was the first gas crisis,
that is when we had to buy gas on days when your license plate had a certain number.
Back then I bought a van and had commercial plates put on,
just to beat the system.

You are right, they probably thought GASAHOL was here to stay,
but then there was a glut of gas and the price came way down.
What is interesting is that Brazil went through the same
crisis, but they decided to keep producing the fuel and now
it is there main source.

According to Boat US magizine Seaworthy, The first choice would be to empty the tank completely. Since that is most likely not going to happen the second choice is to keep it at 95% full to cut down on condensation.

This I did not know, The NFPA national fire prevention association recomends this to cut down on explosive fumes in the tank.

I have been kicking around the idea of installing a air dryer on the vent line so when the tank breathes it will get dry air.
