I just found the problem with my 2000 90HP Johnson outboard motor. The symptom was the motor idled fine and ran fine up until about 3000RPMs then it acted like it was missing and would sputter, not getting above 3500 RPMs at full throttle. This happened even from a cold start. Turned out that one of the four carburetors had one loose bolt and one almost falling out. I tightened both and it runs fine at all RPMs now. I might add it would miss every 10 or 15 seconds at low RPM too. Just thought I'd pass this on to others.
