    Went to change the plugs on my F20 Yamaha and none of my spark plug sockets fit(or any in the set). Any recommendations?

    Thanks

    5/8", 13/16" or 15/16" are the only size plug sockets I've ever needed.
    That goes for vehicles, outboards, and lawn equipment.

    Tow the boat to a NAPA store and pick out the right one

    I have an odd ball plug size on a Yamaha also 18 mm I think ?
