Hello. My name is Tan.
You want the circuit closed when lanyard is attached. The way the switch works is ignition 12 volts flows through the switch to the ignition system. When you pull lanyard off it breaks the circuit cutting off 12 volts to the ignition system.
You are correct on the outboard it is the opposite. No connection when lanyard is attached. On out board it grounds the ignition when lanyard is removed.
Is this all you needed?
