1987 15 hp Johnson just came back from the shop for an ignition problem that I could not successfully resolve myself. Haven't even run it yet, but I know that it went into the shop with two (new) QL77JC4 plugs and came back with two (new) QL82YC plugs. I cannot find QL82YC plugs spec'd for any OMC 2-40 hp between 1973 -- 1990.
Does anyone know if there is any noteworthy heat range (or any other significant or noteworthy) difference between these two (Champion) plugs?
Power pack was apparently the problem and it was replaced after the stator tested out ok. Is there any difference between power pack 586800 (the OEM spec for this motor, in place before the shop visit) and the new 586799 powerpack that was installed by the shop?
I'm not savvy enough to know the difference (if any) between the old vs. new plugs and old vs. new powerpack part numbers. I do know that the motor went into the shop with OEM spec'd plugs and OEM spec'd powerpack, but came back with different (not OEM spec'd) part numbers.
Any knowledgeable, informed input, warnings or reassurances would be welcomed and sincerely appreciated.
I'm not going to put this motor back on the boat until I run these questions to ground. Thanks in advance for any help.
