50-60s magnetos are all the same… just wire an extra wire on each point and hook-up the 2 wires on a normally open switch.
mount the button swicth where you would like to have it…. pushing the button with mutually short the coil primaries and kill the ignition
a safety cord should do the same short out the wires
just make certain whomever stays in boat knows how to restart the engine to pick you up….more importantly when above waterfalls and rapids 🙁
alone…??? would you have a ladder to reboard … using the caviation plate as a step ladder isn’t always easy to do !
if you have 2 blacks (M) on the switch you can tap in on those to. that is what the switch does when it kills ignition
