Now that these things are required can anyone offer ideas for install?
The one I have is a normally open switch. In other words when the lanyard and fork is pulled out the switch makes but in operation that circuit is open. There are only two wires.
For the life of me I can’t think how to mount without using a relay to ground out some circuit.

Required? Just curious. In your state or where are they a new requirement on older boats? They were on Jetskis forever. If the Captain of the boat doesn’t keep the lanyard tied to themselves they don’t do anything. Usually they short or disconnect the ignition. If it is a normally open ( without the lanyard /fork in place ) you should install it in series with the ignition lead. So that would be the wire that is energized when the key is in the run position. So in other words the ignition wire has a secondary switch in series after it’s installed. Normally open but when the fork/lanyard is in place the switch is closed.
If it was put in series with the positive wire to the key then it would enable the starter as well as ignition for the motor therefore someone couldn’t turn starter ( in turn spinning propeller) therefore prevents injuries from prop turning when someone is near it in the water. The current requirements for the starter is more than just ignition.

What happens when you pull the fork?
Still open?

Just the opposite.
Sounds like it's wired into the wrong line.
Switch the wires on the deadman.
Possibly a bad switch. Or your using the wrong wires.

Can you check volages?

It’s new and potted. Thinking now to splice into run circuit with red leg and black leg to ground.

Thanks Fred,you are correct; my reading was unclear in my head. Still might hook one up.
Anyone see a problem with grounding the run circuit to shut the engine down?

If you ground a hot wire, that's a short circuit, and you'll fry the wire. I would get a normally closed switch and install it in the ground wire to the ignition. Then when it trips, it breaks the ground.

Fred’s latest post makes way more sense.
A switch that is always open in any position is broken inside.
Thanks Fred. I was like HuH?

I wear my lanyard anytime I'm running. Think about it. If you go overboard or pass out the boat is still running wide open. Potentially a real danger to you or anyone near by. A hot shoe won't stop boat but it will come back to idle. Stay safe guys 👍
