I recently bought a 1984 johnson 50hp. I have done a few repairs: replaced ignition switch in controls as it was missing key, replaced fuel pump, replaced water pump impeller/gaskets, oil change on lower unit. I hooked it up to muffs and it ran just fine, i ran it for 45mins to let it warm up and figured she was ready for the river. today when i launched the boat it started ok but had a difficult time idling i had to keep the warm up lever on. the gas in the tank is about 7 months old. another issue is it wasnt pumping much water a few drops but not a stream, when i would raise the warm up lever the flow would increase with the rpm. i left the dock it ran fine i gave it some throttle it would run for 8-10 minutes and die without sputtering just shut off. it would right back up 1-3 more times then wouldnt start till it cooled down.
I know i have a bunch of symptoms. obviously the old gas could do it but it seemed more like a coil or cdi box or maybe i did something wrong with water pump and its overheating. I'm thinking the old gas explains it not idling but it killing like i hit a kill switch while crusing at 1/2 - 3/4 throttle leads me to think its not fuel related at all. when it died i check the primer ball it was still firm, i didn't have a wrench to pull a plug and check for spark when it happened. i was thinking putting new fuel and getting it to idle, and doing the blow dryer test to coils/cdi box. im not sure if its overheating just wondering if anyone had some direction for me.
