The biggest hassle about ethanol is it is alcohol so it attracts water.

Our state just switched from the old MTB?? additive to Ethanol. Some of
the stations have stickers on the pumps saying you should check your
boat engine to see if it can handle the ethanol blend or if it needs
some preventative maintenance before running the ethanol blended gas.

I've got an old Johnson 80 HP outboard. What do I need to check?
