sharkbait;

Without your engine s/n it is difficult to narrow it down but here is the harness, item 18 for an '85 50hp.

As the part is no longer available in new condition, search the net to see what you can find, like this one:

Here is a link to a condensed version of the Clymer service manual with electrical diagrams. Let the page load for 30/40 seconds.

Hope it helps.

Re: Looking for Wiring Diagram 1985 50HP Murcury

here is the number ser#6590531 . What I'am trying to do is use the wiring harness that we were given with the motor, the wiring harness was hooked up to an older 150hp motor with a fiberglass cowl and has an older style control box that has a 12 pin power plug.
