BLOWN85

Has anybody done any research to see if you can run E85 fuel in a boat? What are some of the things that you would need to be changed in order to do this? I know that ethanol burns at about 1.5 times faster than gasoline but it does have an octane rating of 100 or so. I am having problems finding higher oct. fuel at the pump in my area and would like to try and avoid having to bring a bunch of fuel jugs to fill my boat if possible.
