Dkoy Posted May 4, 2009 Share Posted May 4, 2009 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? Quote Link to comment Share on other sites More sharing options...
BoxMN Posted May 4, 2009 Share Posted May 4, 2009 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. Quote Link to comment Share on other sites More sharing options...
