I need to get the wires. They are very brittle. What do you suggest. Go to lowes or homedepot and try to buy the same colors and gauge?

Go to an auto parts store and use automotive wire. Most likely if the wires are rotten and go into ignition components you will have to replace the components. You can try replacing the wires but it usually doesn't work due to the wire in the components.

You could also just replace the harness and the components that are bad.

Here is a link to your motor for those parts. http://www.marineengine.com/parts/johnson-evinrude-parts.php?year=1982&hp=50&model=J50BELCNR&manufacturer=Johnson&section=Ignition+System

I would replace the engine wiring harness # 34 in the parts link I posted..

How do the wires look coming from under the flywheel?

Can you show me via online where to get the wiring harness and also the wires. Flywheel?

I posted a link to get parts. Here is the link. http://www.marineengine.com/parts/johnson-evinrude-parts.php?year=1982&hp=50&model=J50BELCNR&manufacturer=Johnson&section=Ignition+System

Open this link and it will show all the ignition and wiring. The harness is # 34. Here is factory harness. http://www.marineengine.com/newparts/part_details.php?pnum=OMC0767968

Here is the aftermarket harness. http://www.marineengine.com/newparts/part_details.php?pnum=CDI413-9915

I am cheap, I am trying to go just buy new wiring and use that. It worked last month when I bought it off the guy from craiglist.For the wiring, what auto store via online and what I am looking at by the flywheel?I will solder heat wrap the wires. What ends should I get for them?

Any auto parts store will carry wire. You will nee # 14 ring terminals for 14 gauge wire. All of the wires. That come from under they flywheel.

Thank you....Tan

Can I just use one color?
