If you're doing seasonal maintenance on a small 4-stroke engine, replacing the spark plug is one of the lowest-cost, highest-impact steps you can take. A fresh plug restores easy starting and smooth idle on engines that have been sitting over winter.\u003c\/p\u003e\u003cp\u003eFor marine outboard spark plugs, see the \u003ca href=\"\/products\/champion-ql77jc4-marine-spark-plug-828m-4-pack-mercury-4-stroke-24-ql77jc4\"\u003eChampion QL77JC4 #828M\u003c\/a\u003e for Mercury 4-stroke outboards or the \u003ca href=\"\/products\/champion-ql78yc-marine-spark-plug-938m-4-pack-long-reach-4-stroke-outboard-24-ql78yc\"\u003eChampion QL78YC #938M\u003c\/a\u003e for Evinrude\/Johnson 4-stroke outboards.
