  • Designed for 2-cylinder (20 HP and 40 HP, 1970-1981), 4-cylinder (50, 65, 80, and 85 HP, 1967-1975), and 6-cylinder (90, 95, 100, 115, 125, 135, 140, and 150 HP, 1966-1979) Mercury/Mariner outboards
  • Harness exits through the side of the lower cowling for proper fitment
  • Color-coded wires for straightforward installation and connection to power pack and boat harness
  • Replaces over 30 Mercury OEM part numbers including 37628, 38072, 38920, 39177, 45070, 46285, 52770, 52771, 84-66055, 84-71443, and many more

CDI Electronics specializes in superior ignition and diagnostic solutions for the marine industry, offering reliable performance at a value price point. Professional installation by a marine technician is recommended. Note: Fuses are not included with this harness and must be purchased separately. Matching boat-side harness (CDI 474-9550) may be required depending on your application.
