A guy at work at his fail on his 2003 last year(40HP) and now my 2004 40HP isn’t running right, it feels like one cylinder just cuts out at times and the engine seems to flood out when you let off on the throttle. Mine should be covered under the extended Mercury warrantee. Just wondering if there are more out there.
If it wasn’t for the warrantee, I would have cracked the ECM open and be looking for a problem. I have the feeling it could be cold solder joints that have cracked and making an intermittent electrical problem- like the wiper circuit boards in the pre-99 GM trucks
