my OMC came with electric choke, 12v when key is on applied to bi-metal spring inside choke housing, spring heats up and slowly opens the choke. Don't know what kind of set-up you have whats it look like, did you not get instructions.

Electric chokes need 12 volts when the ignition is on, not all the time or your battery will go dead and the choke won't work properly.

Connect it to 12v ignition switched and it'll work great.

No, your ignition switch is fine, and we're talking about "ignition switched 12 volt supply", not the switch itself. That's an option, but I wouldn't recommend it.

You need to find a convenient source for 12 volts that is switched on when the engine is running. There's more than one place for it on your engine, but I'm not familiar with it. You may need to look at a wiring diagram.
