Spark Plug Suggestions

[4link1955]

What plug do you guys recomend running in a 1977 140hp Evinrude? I'm looking for an all around good plug that will be best in performance. I'm not interested in doing any trolling so thats not a factor. I cruise with this boat and waterski too so it's going to see wot alot.<br />Thanks:<br />Jason
