for 1975 Johnson 50HP Model 50ESL75.
Switch is built into the throttle controls.
The type I had was very simple.
It was a small plastic device that fit around the key.
It had a lanyard (string) and when it was pulled it forced the key to turn and therefore turned off the engine.
Does anyone know where one might be available?:D
If not, can you suggest an alternative that might be simple to install?
