I was going to change the spark plugs on my V-6 300 HP 4 stroke Zuki but my spark plug socket will not fit into the spark plug recess on the valve covers. The plugs are 13/16" (20.6mm) and I can't find a thin wall socket that will fit into the plug recess. My 13/16" is a 3/8" drive with an O.D. of 1.05" and it's way too big. Anyone out there have a part number or manufacturer for a socket that will fit?
