Do your own experiment removing alcohol

Ethanol will absorb some water, I think less than 1%, so it can remove some water from the tank vs regular gas. But, once it surpasses that small % it will then permanently phase separate. The alcohol will come out of the gas & merge with water as a separate layer on the bottom of the tank. It will never go away and must be drained.

So you are saying that the fuel pickup (at the bottom of the fuel tank in most systems) will refuse to pump this phase separated (lets say 95% ethanol/5% water) mixture through the fuel system? That has not been my experience. Ever heard of water injection?

A modern computer controlled fuel injected gas engine, if it can get started on the above referenced mix, will pump it through and burn it. It may run like XXXX until it's warmed up and purged, but it will run. I wouldn't leave it in the system for long because of the corrosion/gum potential.

On the other hand, if you get a real slug of water in the fuel tank, well, not much can deal with that other than a drain plug.

Did you read this thread?

Yes, thank you, I did read the thread. I do agree with the engineers from Mercury Marine. I have met several of them and they are very bright competent people. That's why their products are as good as they are. Ya see, it's like this. As engineers, we all had to take the same prerequisite classes in years 1, 2, and 3 of college. Those include chemistry, physics, calculus, statistics, thermodynamics, statics, dynamics, strength of materials, stress lab, etc. That's why we think the same way. As such I don't feel the need to downgrade my education with a rehash written by some editor at Boatus magazine. Those journalism guys usually got a little squeamish when anything but the Kings English was written on the board in real science classrooms. Greek letters/symbols, . . . . well, forget it.

That said, the article may be perfect for you, and if it is, well great. Get your formal education out of a magazine. What degree programs do they offer?

Now, are you going to answer my question, or, just obfuscate, duck and cover, then defer to someone else. I'm speaking from my own personal work experience. How about you? Those are rhetorical questions so you need not reply to anyone other than yourself.

I am not going to try to make negative comments about you and your education or whatever, like you just did about me. I graduated from one of the best universities with a math major and then got an MBA in finance. So I also had calculus, physics, chemistry, statistics, etc. I understood the article. I see you tried the same condescending approach to Mex, a knowledgeable poster with many good threads.
