Plug Question

[CATCH 22]

Anyone know about not running NGK's in a Johnson? I was told only run Champions by a reputable Mechanic and want to hear the many motor Guru's thoughts on the matter. And if so, what plug do you recommend? Thanks

[BAD BEHAVIOR]

See what your owners manual says. Mercury advises only NGK plugs. I wanted to put performance plugs on BB and I was sternly told not to by my warranty man. He buy the way is primarily a Johnson/evinrude man.

[Bow'd Up]

Go with what the owners manual suggests. Can't go wrong with that.

[Mook!]

I got a couple OMC shop manuals (the real ones, published by OMC for authorized service centers, not the junk ones from the book store) for a few different motors. All of them say Champion only. I ain't one of them gurus you're talkin bout, but Champion ain't really expensive, so why use a different one...
