The ethynol DEFINITELY eats some of the older rubber compounds that were used in fuel systems resulting in a nasty sticky sluge and lots of fuel leaks.
If you have any old rubber parts or gaskets in the fuel system of your boat, (or car, or lawnmower, or whatever,) you must replace them all. Don't forget things like the accelerator pump diaphrams and other tiny internal pieces. I don't know the exact date to say is the point to worry about this, but in my experience by 1989 all of the rubber used in contact with fuel seems to be OK. Before that it is a crap shoot whether you have rubber that is going to melt or not.

Also in any older equipment that has open vents for the fuel tanks the ethynol evaporates off pretty quickly, leaving behind only the less volatile componants of the fuel. If you often top off before using nearly all of a tank this will gradually degrade the condition of the fuel that remains, and diminishes performance. In the extreme it can get to the point where the engine hardly runs. Don't confuse this particular diminished performance problem with the separate situation of gunked up fuel delivery.
