Re: 2000 Johnson 115hp WOT woes
coils, power packs, and stators can all start to fail when heated. there are about 6-7 pages in this link, for electrical testing, find his motor. also you can take the boat out, with an induction timing light, and when it starts to fail. check the spark with the timing light of each spark plug lead. will it run wot when it's cold, and then drop back to 3500. are you sure it's not running hot, and the slow mode kicking in, to keep from burning it up. slow mode usually brings it back to 2500rpms. if it will not run wot, when cold i would consider putting a carb kit in it , and besure to remove and clean the high speed jets, that are deep inside the front bottom drain plug. do a little testing before the doctor.
