    I ran the serial number you gave me. V-2000 motor correct? The parts listing gives 2 wire harness part number for that motor. I assume that the one you cannot get is a 84-87294a1, the list also has a 84-96220a4 which is available. I would contact mercury marine at and run the number by them. It is going to give you an error message. Look at the find your serial number link and do what the text tells you to do. Hope this helps. Gary.

    Here is a web site that you can check your parts numbers at. Its pretty good info if you don't have access to the microfiche. Gary

    I can get you an aftermarket replacement for the 96220a4. List is $150, you can have it for $118 plus shipping. Email me if you want it. I don't stock it, so it will take about 10 days.

    Thanks, Ducky. Actually,Along with the harness, I need a throttle/shifter/control assy that will work for that eng. Do you know if a later mod. assy can be used? What are my options? The Merc. dealer in this area is not much help. Tim smile_sp
