Replacing stop switch for 1971 evinrude 9.5

Hello, I bought a small boat that came with a 71 evinrude 9.5. It’s in really good shape but the wiring for the stop switch is shot beyond repair. I’m hoping to replace it with a kill switch but am not familiar at all with how that works, especially with the old school reciptical connectors. I’m looking for a cheap alternative to the original switch that is very expensive. Any help/advice would be greatly appreciated.
 
How it works: There are two black wires going to the switch. Switch connects those two wires together to stop the motor.
 
Wires go to each points set. When touched together they ground out points. Why? Because when one set of points is open, the other is always grounded. Cylinders fire alternatively. Check out this nice switch I found for you.

Thanks for the info! So for the wiring do I just use waterproof copper or how do I go about that?
 
Yes the wires should be good quality. Mice get em? These 9.5 are perfect homes for mice. Why? Mice want a home that offers protection from their greatest natural predator. They want to fit into the smallest holes possible....anything bigger....a weasel can get in. Many outboard motors offer the perfect access....not too big, not too small. 9.5's are often destroyed. Store in a mouse free location whenever possible.

Okay, and how do I go about changing the connector pieces? The part that is still intact has the old school reciptical quick-connect. Should I strip that out and swap it for a different connector piece?
 
Yes those old school were cool, but your gonna have to go with newer school type. Just make sure they are good quality 16 or 18 gauge.
 
Ha! Great idea, but I'd probably loose the damn cover. Got 100 motors with cowlings around here. Got 3 cats, however.
