Steve, if you haven't been experiencing any trouble with your motor and have been using ethanol gasoline, consider yourself lucky. My Mercury 15hp is a 2000 model and for the past couple of years it has been getting worse. Missing, an occasional backfire and hesitation upon acceleration. I finally found a couple of stations that have ethanol free gas and the problems immediately disappeared with the first tank. If at all possible, try to run the ethanol free gas. Let's hope Arkansas doesn't make the same idiotic decision as Missouri and make it mandatory that all gasoline have at least 10% ethanol.
