I've been using ethanol blend pump gas in older outboards for a long time, with no problems. I used a 1966 Evinrude Fisherman 6hp on 10% ethanol for years. As far as I can tell, the only issue is that old fuel lines and seals tend to dissolve. On that old Evinrude, before I began using ethanol I replaced all of the seals, fuel lines, and fuel pump with new ones made from modern ethanol compatible materials. A 2006 Nissan is likely to already have been built with compatible materials, but you could contact the manufacturer to make sure. Even if your engine is compatible, you'll have slightly more power, better fuel economy, and less water in fuel issues with non-ethanol gas, if you can find it. Still, I think it's worthwhile to setup an engine to handle ethanol gas so you don't need to stress about using it by accident or in an emergency.

Tom, I am in the process of selling my M-15 and of course the outboard engine goes with the boat when sold. I really would like to hear your comments on Ethanol in the gasoline that I have been using in my 2006 Nissan 3.5 hp 4 stroke outboard. Will my outboard be ruined? Where in California can I get pure gasoline?
I have been going to the suppliers on the Sacramento River area for the fuel for my C-Dory 22 with two Hondas on the transom. I hope the suppliers were giving me accurate information when they told me that the fuel was "ethanol free"... ---Larry in Sacramento,Ca
