1994 Johnson 115 565 hrs
Engine starts idles runs fine.
after 10 to 15mins it loses power and drops off the plane losing about 1500rpm. only when reeves are between 2800 to 3800pm. I
throttle on/up to try to compensate loss of speed and reeves and then after a few seconds of playing with the throttle it bursts back into life. I then have to throttle back to reduce speed, then again drops rpm.
Ive replaced plugs , coils, then the computer box thing before stator, pumped the fuel primer, pushed on choke ???? can't fix it.
Above the 3800/4000 rpm it was running fine until the last tome I used it when it completely has a split second total switch off then back on, it did that twice felt like the boat hit the sand. so haven't used it since.
all compressions are good as well.
whats my next move if any one can help ??
