For those who may be wondering...
These plugs (QL77JC4) differ from L77JC4 in that the Q indicates an inductive radio noise suppressor type plug. Otherwise they are the same. In some outboards the EM radio interference from L77JC4 plugs can potentially interact with the charging/ignition system. Obviously this means it can interact with radios as well so take that into consideration. In a pinch I had been running ngk plugs and they made the engine run rather poorly, causing misfires, poor fuel economy and rough idling. My outboard (94 Evinrude 70hp) calls for these Q plugs and they definitely make a difference in the idling quality.
