    Indexing Plug s Question

    When indexing plugs how far off the deflector pins is acceptable? The factory has the port plugs on my 150 aimed exactly at the injectors but the starboard plugs are 90* to 100* past.

    Re: Indexing Plug s Question (Springseeker)

    You index the plugs off the centerline of the injectors, don't be concerned with the pins as many of the motors do not have them.

    The open gap of the plugs can be up to 90° on either side of the injector, 180° total.

    I know Seahorse has already answered your question but all the info you need on indexing plugs on an Evinrude can be found at boatsetup.com You will need Adobe Reader in order to open the page on how to index plugs
