Got a 60 HP Mariner that started running rough at low speed (Upto 2800 RPMs), also idles so rough I had to set the idle up to keep it running. Put new plugs in and ran some Marine cleaner through it but no change. Any ideas?

take the plugs out and have someone crank over the engine and see if all the cyleneders are firing,you may have a coil that isn't firing at slow speeds.
Thanks, I should be able to get it in the shop by next week. Bad time of year to have a problem.
