    Rough Running 25 hp Johnson

 I need help/advice for a recently acquired 1988 25 Johnson that has a bad cough. Essentially the motor coughs when started and maintains that cough to the point where no power can be developed. I've had the local mechanic looking at it and he did a few things with the carb/Fuel system (Cleaned, new Seals/gaskets, checked for cracks in body etc.) to no avail. Motor has strong compression (125 psi) in both cylinders, Fire is great on both coils, Reed block is intact so I'm lost as to what could possibly be causing this problem. All advice is appreciated.

   May be a gasket from stratos268 (192.195.167.53)  6/14/2004 9:12:00 AM
 I had this exact problem with a 1988 25 hp Evinrude ( the same motor) It went on for months before I finally found the problem. When you pull the carburator bowl apart at the very top, in the center of the bowl you will notice a small gasket that seals between the gas inlet to the throat of the carburator and the jet. That gasket was too thin to allow for a good vacuum to suck in the gas. To make it simple, it was sucking air instead of gas causing it to lean out. My solution I just put in double gaskets, bolted her up and problem was solve. This is quite simple to try, when you have the bowl off, it will be in the center at the top of the bowl. The best I remember the gasket is about 1/2 inch across with a 1/4 inch hole. This might not fix your problem, it did mine. Hope this helps, email me if you have any questions.
