There are a couple possible issues. However, there are 25 HP Johnsons that go back to 60 plus years. So, it might help to know which one. I'm not at all sure you can do what you are trying to do.
It might be better to have an OMC mechanic check out your wiring. The key switch grounds the ignition to stop the engine on some models. Other models have a relay in the system......
