I need some help with this please. I have a 2000 225 Ficht. I have been told different things about indexing my plugs. Some have told me I do not have to and others told me I need to. The digram I saw has indexing for 98-99 motors. What is the deal do I or dont I????:doh Also now that I am able to use the QC10WEP plugs does the gap size change?? Do these need to be indexed???
