" Just got an old boat with an Evinrude SportTwin 9.5 HP motor, vintage 1965. I have cleaned up the motor and it runs great but ONLY WITH THE ENGINE COVER OFF! It runs with the cover on but it struggles and is obviously lacking power. When I added some new gas to the tank (that contained who-knows-what) it ran for about an hour but then it was hard to even start it. I already rebuilt the carb, thinking this was a needle valve, float, or air leak problem -no real improvement.
Could this be a problem with the fuel supply equipment and not the motor? Fuel pump symptom? "
