Ok, where to begin?
I have a 1988 Evinrude VRO 140 HP that starts fine and will run up to about 4500RPM although seems a little week/slugish and takes a while to get the boat out of the hold. Then sometimes after about ten or fifteen minutes I will get a small kick/shudder and the engine will pop into full life. The revs will go up to around 5500rpm and she sounds absolutely perfect. From here if i stop for a fish and restart she will jump out of the hold and run perfectly for most of the day however sometimes after stopping it will go back to acting up and only get to the 4500 slugish RPM. I have tested the compression on all cylinders and these are all fine (within 5psi of each other). I am currently tracing all of the wiring and cleaning all the terminals. But where to go from here I am unsure. I have a manual and am currently working through that however I am waiting on the Flywheel removal tool which is still some weeks away. Any help would be greatly appreciated.
