What's the size of the gap in a spark tester should I have for 1990 115hp Mariner?
I bought a spark tester at a local auto parts store but I don't know how large of a gap it needs. I've seen a few posts say the gap should be 7/16 of an inch, but I'm not sure if that's for all outboards or just the few in the posts I've seen.
Thanks,
Steve
