I have a 1995 Evinrude 25 HP model number E25RLEOR that set is storage 10 or 12 years. I have replaced the lower unit seals, thermostat, plugs, new gas tank and hose and connections, cleaned the carb, and rebuilt the fuel pump. The motor starts on the first or second pull from a cold start and idles and runs perfect until one of the three following things happens:
1) It will be running at WOT for 3 minutes, 5 minutes etc., and suddenly miss as if you hit the kill button for a second or two- and the just pick back up and keep going.
2) it will be running at near WOT or at WOT and I will feel a slight miss for a few seconds and then it will smooth out and run fine.
3) it will be running at WOT or near WOT and it will miss like in item 1 above, but it will continue to miss really bad until it reaches idle and then it will idle for 10 seconds or so and then take off running fine again. When it is in this missing spell, if I try to accelerate, it will continue to miss badly. If I just wait 10 or 15 seconds, I can then accelerate and it will not miss at all until one of these three things happens again. That might be 3 minutes or as much as 20 minutes.
I have suspected that it might be getting air into the fuel line or have a leak in the vaccum line that runs the fuel pump- but I can find nothing. The motor smokes bad on start up but the plugs do not foul and appear to be normal operating color.
Any help will be much appreciated. I bought this to fix up and sell, but I won't sell it until I can fix this issue !!
