Misfire

[Jgranger01]

I have the Mercruiser 5.7 liter and I replaced plugs and wires started it up and it was running pretty good for a a good 5 min. Then all sudden now it’s misfiring and blowing white smoke out the carb. Video attached. Any idea? If the plugs were in the wrong cylinders would it have ran descent for 5 min then stop?
