Isn't that what Fountain uses?? we should be better off with the use of Ethanol correct??

They are aluminum. I would suggest changing the fuel filters frequently (especially the first 10-20 hours). I understand that ethenol will "remove" any build up or debris that is in the tank. We have been receiving a lot of questions concerning ethenol. I called Mercury and their stance is; it is better with no ethenol, 10% blend is ok for their motors, any more than 10%can be detrimental (corrosion and deteriorates rubber). This info is straight from Mercury's dealer tech department.
