From what I have heard, they are talking about running it in the FX boats for the marathon jets, keeps things equal and is easier on engines...If you decide to run it in your jet boat, the temperature has to be controlled warmer than regular gasoline, I would also recommend running synthetic oil to prevent "wet oil".
As far as I know, there are very few places to by it in "Arnold world" (Cal).
I have been using methonol for several years as a fuel addative, it also used to help get a borderline car to pass el smoggo...I guess the new testers are smarter and can catch it, I guess it really cools down the exhaust temps lowering the NOX (oxides of nitrogen)...

One cool benefit, it is more hygroscopic (absorbs water) so water in the fuel is less of a problem than regular gas, but really hard on carb gaskets, hoses and pump diaphrams. They make alcohol specific components and are normally blue or grey.
