EPA approves 15% ethanol . . . .

All tanks are vented to let the fuel flow. Best thing to do is every fill up is add Starbrite Startron or the other one I cant think of the name of.

It would,but that would be way more trouble then its worth. Shelf life is still 90 days or less. Just to clear up what I said about newer motors running 15%. The reason a older outboards will not tolerate 15% is because as most know ethanol is alcohol. The biggest problem you run into is the alcohol breaking down carbon build up,fuel lines,rubber gaskets,fuel pumps,ect ect. In other words if you have a older motor that was just rebuilt and run 15% from day one you would be ok. Makes me want to sell my boat and get a hobie,ridiculous.
