Listed here is a NEW Single Mercury Spark Plug Wire / Cable.  These are all Genuine OEM Factory Mercury Spark Plug Cables NOT cheap Chinese aftermarket replacements.  Will not come individually wrapped since the sets are broken up to be sold individually.  The part number for these wires is 84-881908t or 881908t and usually come in a set of 6 from Mercury but sometimes you just need one so they are for sale here in singles.  These are NOT old left over stock and came off the assembly line on 12-11-2023 (mfg decal can be seen in pictures).  This is the plug wire used on many Mercury engines both 2 and four stroke from the late 1990s well into the 2000s  (Some of the smaller 2 stroke engines use different wires so please contact me if you aren't sure).  These are NOT aftermarkets and for reference Mercury (to the best of my knowledge) always makes these with one brown and one grey plug boot.  They also have a dab of green electric grease on the inside of the boot.  This can clearly be seen in the pictures.  Beware of knockoffs being passed off as factory that look similar.  These are stored in a climate controlled parts room to prevent deterioration.   If you have any questions or need help with compatibility please feel free to contact me before purchasing and I will help you to the best of my abilities.  Thank you for your interest.  Steve MMSLLC :)
