The video in the link below has recently been added to the E-Nation video archive.
This video was produced by the BRP/Evinrude Technical Information Team, and highlights the steps required to correctly index the spark plugs.
Thanks for the info on indexing spark plugs on the E-Tec 135hp. Looking for verification of where the green zone woud be when installing and indexing these plugs.
Would the green zone be close to where the fuel injector is located on the cylinder head ?
The center of fuel injector or the small allen screw-head by the sparkplug can be used as the centerline when indexing the plugs.
You have 180° of total leeway to position the open gap, 90° on either side of the centerline.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.
The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
