I have a Evinrude 1976, 55 hp. It starts and idles ok. but when I put it in gear and try to excelerate I have no power and it wants to bog out or dies. I checked the plugs and they are new and clean. I beleive that my problem may be either my fuel filter or pump may be clogged. It is failing to supply gas when trying to excelerate.<br />Am I looking at the right problem or could it be something I am overlooking.<br /><br />P.S. It was running fine and problem just happened. Son put old fuel in gas tank.
