have a 1992 mariner outboard that cranks and runs fine, but while idling it will occassionally "miss" and the idle will momentarily drop. it did this last season some, not sure if it did it the whole season. i have changed plugs and it made no difference. when it does the skip, it usually does not cut off, but a puff of oil looking smoke usually comes out. one other question, this weekend while getting it out to start the season, the muffs fell off and i ran the engine for maybe 30 seconds or so without water. engine was cold and after i reinstalled them water still seemed to come out the "pee hole" like it normally does. should i worry about the water pump wheel? thanks!
