3 times so far this summer problems with gas. 15 hp evinrude, if it sets very long I have issues. Doesn't want to start, even with all the little tricks to help but an hour later it will fire right up with one pull. Get to the lake and it will start right up but only seems 1/4 throttle all the way thru the channel, about 10 minites. Then it will hiccup a few times, nuetral, reverse and then take right off and be good the rest of the day. Maybe it is only running on 1 cly til it warms up or maybe the gas gets old in carb or line, just happens when it sets for a few weeks cause of weather or traveling to NY, if I am using it every day no problems.
