All good and logical tips above and in the last issue of Shallow Water Angler http://www.shallowwaterangler.com/
they had a good read on this subject and that article alone was worth the price of the magazine in my opinion

Ethanol does make for a very good octane booster, but what seems to be the concern of some is how many times is X amount of fuel is getting treated with the Ethanol blend? Thus E10 could equate to more like E15 or even higher when exiting the pump.

Ethanol also does not have the same amount of BTU's (about half) as regular gasoline so I do not see E85 as a real solid solution to buying less overseas oil either. From the test results I have read, the same Chevy truck running E85 went from 15 to 10 MPG thus your cost per gallon was even higher from burning more of it Something they also fail to mention on the TV ads now don't they...

I say such because your Outboard "may / will" do the same if you buy your gasoline / white lighting blended fuel above the tested and allowed 10% mark. Thus you may find out (the hard way) that the fuel you are trying to burn, has been treated more than once with Ethanol.

Here again, if you are not tracking fuel burn rates you may "suspect" such, but will not have the hard numbers to compare these trends and really know. Reading the numbers though only helps when all things are equal meaning... The engine is NOT in need of any service work like a Spark Plug replacement or having plugged and dirty fuel injectors. Just another good reason though to track fuel usage, this so you can change fuel suppliers if needed
