Saw another video on kill switches for small vintage outboards that said to use a 2-wire kill switch attached to the two magneto contact points. Tried it on my KG-4H and it worked. You don't need a 3-wire switch. The reason is closed points provide a path to ground for the primary coil so that it builds a field and when the points open, this field collapses leading to the spark. But with a closed 2-wire kill switch when one of the points open, the related coil is still grounded at the magneto contact point of the other coil so the primary fields never collapse and never produce a spark.
Great safety feature - thanks for posting
You always have great content, can't wait until you get the snowmobiles out
Thanks! Excited for snow!

Makes sense to me, I just ordered a kill switch off from a hydroplane website and this is what they sent me.
The suspense is killing me to m ready to see it running on the water
Video is up!
Yeah, good idea. Goes back to my prior question about how "nosy" they become coming off throttle at speed! Hopefully you never need it.
Cool. Hurry up and show us how it goes you’ve obviously tested it out and filmed it.
Next video is on water testing 👌
