I have a Johnson 8hp outboard on my small RIB. It has been working great for a long time, until last week. After running with it for about 30min, it suddenly dropped down to idle speed and would not accelerate. It did not die, it was still getting fuel, still had a spark, etc. But even turning the throttle full open would not give it much power. And even in neutral it would not rev very high at all.
I checked simple external things like the fuel line and the prop, but everything looked fine. I'm wondering what troubleshooting I could do to narrow down the cause of this problem. Or maybe the cause is common and already well-known?
