Spark plug gap question
I can’t read the model number anymore on my 2003 Johnson 175. I remember it starting with J 175 & think the rest of it is GLSTE, but not positive. It’s a carb motor if that helps & I know it takes champion QL78YC plugs. Was it thirty thousandths for the gap? Also what would the plug wire setb number be to replace them? Thanks

Les I think CDI Electronics wire part number is 931-4921. The plug gap is .030. Please take a look to verify for yourself.
