    2005 225Etec HO Spark plug gap and indexing question

    HI All,

    I have a 2005 eTec 225 HO. I have new QC10WEP plugs. Could not find what the gapping should be set to.

    Also don't know if the old plugs where indexed when installed so the Sharpie trick may not be the best way to index the new ones. Is there a marking on the motor for the proper spot the plug should be pointed to? Tried to watch the indexing video but it is no found.

    Thanks for the help
    cheer

    The correct spark plug chart is posted above as a stickey. Gap points towards the injectors.

    thanks I saw the chart, and i have the correct plug. was just looking for pointers on where the injector lineup is. On my old yamaha there was a Dot or screw to tell you the proper location. Also what should the gap on the plug be set to?

    The last video explained it very well and gave information on torque too and what grease to use where. It should be pinned at the top.
