I have some QL77JC4 plugs left over from a previous engine. Can they be used in my 97 J115SPL XJ115HXEUA? Or do I need to use the QL82C?<br />Still haven't got the manual :( <br /><br />Thanks<br />Dave

I use the QL77JC4's in my 60* 150 all the time. No problem.

I put QL77JC4's in every 4 or 6 I work on. <br />I don't do Fitch's

Dave, the QL82C is the recommended plug, but it's in the same series as the QL77JC4, which was the original plug and will still work fine.<br />I'm not sure you could tell any difference unless you Idle a lot...the 82C is a Tad hotter.
