Substituting a different heat range plug can cause fouling (too hot) or pre-ignition (too cold), so always match the plug to your engine's specification. If you're seeing heavy carbon fouling on your current plugs, a hotter plug like the L78V may be appropriate — but confirm with your engine manual or a marine technician first.\u003c\/p\u003e\u003cp\u003eFor other Champion marine spark plug options, see the \u003ca href=\"\/products\/champion-spark-plugs-ql77jc4-828m-4-pack-12198-24-ql77jc4\"\u003eChampion QL77JC4 #828M\u003c\/a\u003e or the \u003ca href=\"\/products\/champion-spark-plugs-ql78yc-938m-4-pack-12217-24-ql78yc\"\u003eChampion QL78YC #938M\u003c\/a\u003e.
