hey Englishman, glad to see your summer fishing improved. it is great to hear of your exploits. Plug indexing is a bit of a evinrude "characteristic" . It really just means having the open end of the plug facing the injector. When installing plugs mark the open end of the plug on the porcelain with a sharpie. When you install the plug the "index" (your sharpie Mark) needs to line up with the injector mark, give or take 30 degrees either way. Occassionally you will get a plug that will not line up and you need to try another one.
Most outboards benefit from indexing , but it is essential in Evinrudes.
Hope that helps , beemer
