'86 Mariner Idling hard

2 posts in this topic

I have a '86 Mariner 40hp that idles hard when in neutral and when going at slow speeds (enough to shape the boat pretty good). Is this natural and is there anything I can do to fix this?

Sounds like maybe either bad gas or you need to raise the idle just a tad. That ust not be the Classic 50 motor (2 storke 4 cylinder)? Cause if it is, then that is definetly not normal, the Classic 50 idles smoooooooth as butter.
