If you the motor with rotten wire harness this is the answer. Way easier than trying to fix the old one

    Fantastic Product
  

*by R***I on Reviewed in the United States 🇺🇸 on December 29, 2018*

The old harness was terribly corroded.  This product arrived quickly and in perfect condition.  I used it on a 1980 85hp Mariner.  This product was not an exact match, but installation was simple.  The wires color code perfectly so just detach the old and attach the new.  Power pack has clear color coding.  There are a couple extra (i.e. tachometer) and the plug didn't match.  If you order this for a similar motor, then you must order the corresponding boat harness or they won't plug into each other.  If the wires and insulation were slightly thicker, then I would have given it 5 stars.
