I would appreciate a little help. Ive been a basscat owner for about 8 years and until now have had no problem with Fuel. I currently have a 2000 Cougar with a 225 Mercury EFI and have been reading some of the recent posts on the Owners Board about fuel and the problems with Ethanol and Alcohol additives. My problem lies in that in checking this past weekend at all major brand gas stations locally and off brand stations, all have approx. 10% ethanol or alcohol listed on their pumps. What chance do I have other than keeping tanks full and hoping for the best. Am I going to do major or even minor damage to my engine of the fuel delivery system? Any help will be appreciated. Mike
