The wire color is light blue with no mfg number or any number. Plug ends are bright shiny red and look nothing like quicksilver brand. No original packaging. Not even a correct part number anywhere on packaging. How could this be oem from quicksilver. Very disappointing for the price I paid for oem parts.

Really happy with the quality and look of my new wires, not to mention that the boat runs like it should now.
