Ok i have a mid 70s model starflight 85hp evinrude outboard. I have rebuilt the carbs, resealed the lower unit, had the timing set and have replaced the powerpack. The guy who works on my engine detemined last week that i had a bad powerpack. The motor was firing on 1 cylinder. I replaced the power pack this morning and the engine now fires up and idles perfectly. I took the boat out to the lake today and got up to full throttle for about 2 min. The engine begun to bog down a couple seconds then went back to full throttle for about 10 min. We then cut the motor off and enjoyed the lake for a while. Beutiful day down here today 75 degrees all sunshine. We started up the boat again and preceeded to go full throttle again and the boat began to bog down to about 1/2 throttle. I tried pumping the primer bulb to see if I had a feul delivery problem. The bulb was tight and the motor did not respond to me trying to pump the bulb. I was told by the guy who works on my boat that the stator coul be going bad when it gets hot or that I may have fould theplugs when I tried to run with the bad powerpack last season. He told me to try changing the plugs and gas and see if that helps. He would check the stator for me next week. We had the flywheel off last week and the stator looks like it has been replaced not long ago. It is definitly not the original. Can someone give me a few pointers on this problem?
