I have a female friend who owns a boat and reported that her

cause an engine not to start or die while in service. She has a
outboard. I said I was not aware of any issues, and had seen nothing
major reported in the press. I said I had an I/O with a Chevy V6 and
would not be expecting any more difficulties than would be the
case with my car. She then asked if it could be just an issue
with outboards.
I haven't asked my marina guy about this yet. I did a little Net
research and couldn't find much except something about a possible
reaction with fiberglass fuel tanks.
Can someone clear the air on this issue? She seemed quite
concerned. (I'm not.)
Many thanks for your help!

Thanks for mentioning that fiberglass fuel tank issue again. It's been
covered before but it can't be covered enough until everybody with a
FRP fuel tank knows *not* to put ethanol blended gasoline into it.

I'll bet there could be some issue with runability- particularly when
the gas has been stored in a fiberglass tank. As the ethanol dissolves
the resins in the laminate, it's quite likely that the chemicals stay
in suspension on the gas/ethanol mixture. It could maybe and might
change the combustible characterstics of the fuel itself?
