Re: replacing wires 115hp merc

When you say battery connectors, what exactly do you mean by that?

It is a good idea to replace any wiring that looks suspicious; for example, charred or cracked insulation, corroded ends, etc.

Easy to replace the distributer wire, just make new ones. Not sure about switching the whole units though, but with more info on what year and models, someone here would know. I'd just do the wires as its so simple. On the batt leads off the harness, slice off what you have to to get to good wire. Get some new 8 gauge wire, butt connectors, and new cable ends. Tape up and your done. I'll post a pic in a second, as I am working on one right now. The wires are not connected yet, as I need to go to town and get some butt connectors

You may be able to swap the entire distributer. Just do yourself a favor and get a service manual. The timing on these motors is key to thier success. Too far advanced, and you have a 350lb anchor.
