Hi everyone, new boater/fisherman here.
I have a 2003 25 hp mercury outboard. It ran great last time out. Today it seemed to have idle problems. It would die unless you set the fast rpm lever up some to keep it running. Then you had to be quick and shift it into gear and throttle up to keep it from dying. It ran fine thru all throttle settings including WOT. Same gas mixture as previous time out when it ran fine. I do not have a manual yet. Looks like there might be an idle setting on the black rubberish prime button but that seemed not to make any difference whether it was set full clockwise or counterclockwise position. Any thoughts to what might be the problem?
