1999 Johnson 15 HP 2 Stoke and Spart Plugs

[Calibra]

Hi

I've just read this thread about spark plugs for a 9.9 / 15 HP Johnson and I'm wondering if I am using the wrong plugs. http://forums.iboats.com/forum/engi...k-plugs-on-evinrude-9-9-15-hp?_=1444167210255

I've got a fully rebuild 1999 2 stoke Johnson engine. It runs really well, now coming up with 30 hours

I've been using these spark plugs, [h=1]2x NGK Spark Plug Quality OE Replacement 4122 / BR7HS[/h]

Do you recon I should swap these out for something else?

Thanks

James

The OEM recommendation is Champion plugs, QL82C gapped at 0.030".
There is nothing wrong with NGK plugs per se, high quality product; it's just that they are never exact matches for Champions.
