Mercury Outboard Internal Engine Harnesses
PLEASE READ THESE DESCRIPTIONS
1 out of 2 people buy the wrong
harness. Internal harnesses are about 18 inches long. The
internal harnesses go inside the engine cover. In order to
continue supplying handmade harnesses for older Mercury engines
(at a reasonable price) We
must charge a 20% restocking fee on all returns and exchanges of
harnesses. Also, shipping
charges for replacement harness will be charged. Again... please
read the description before you order your harness. Help reduce
the error rate! The error rate is so high on harnesses that we
considered not selling them at all. If you have any questions
contact us: dstiber@aol.com. We will help your select the correct
harness. Our application
chart below is also very accurate. Check your serial
number.
What the above diagram is trying to show you:
All the harnesses orientate themselves the same way if you look at the big pins on the outside. What the V at the bottom of each drawing is showing is what direction the harness turns inside the motor in relationship to the two big terminals. Look at your big plugs and then see if the harness wires turn up, towards the front, or towards the back of the motor.
#2770 heads the wires up. #3369 turns to the back. #5532 turns to the front.
The Mercury outboard boat harness (external) is at bottom of this chart. That is the harness that goes from the engine to the control box by the steering wheel. The external harnesses are about 20 feet long.
