Okay folks,
As a teacher, I know that there are no stupid questions... only inquisitive idiots, so here goes:
My engine runs okay at idle and low rpms, however once you open up the throttle it will run smoothly for a minute or less and then the rpms begin to fluctuate, gradually reducing until the stream of profanity from the skipper drowns out the sound of the motor. If I re-prime the bulb, it will run at full throttle again for another minute or so. The tank is vented, the bulb and fuel hose are new. Spark plugs are new. Carbs were recently cleaned and compression is A-okay on all 4 cylinders. But, since an outboard will not run on blue language alone, any suggestions?
Thanks, -K

I've been having a simular problem as you are experiencing-- BUY mine is at idle- I just installed a new tank, new hose and an inline filter - You can see that the in line fuel filter is empty and once you reprime it, the engine idles fine-
Have not had time to take the boat out for about a month and I'm going to remove the in line filter and see how it runs
I agree with Phil. My neighbor down the street has a 1988 90hp Evinrude that was doing the same thing as you describe. We replaced the fuel pump and it works great now.
