I have a 71 so not familiar with one as new as yours. Does it have a gear shift from neutral to forward? If yes, does the prop turn freely in neutral? Pull the plugs put it in forward and turn the flywheel. Is it easy to turn and does the prop turn? I'm thinking your problem is fuel related but making certain the leg is working is important. If it has a slow speed lean/rich knob turn it to a richer setting about 1/8 of a turn at a time until she runs in gear and then keep richening it until it stays running. Get an OMC service manual for it and it will be most helpful. Best of luck, and let us know how it is going. Rick.

Also, could you possibly be running on only one cylinder? In fast idle, pull one spark plug. If it dies, the other cylinder is probably not working. If no change, replace plug and pull the other one.
Have you checked compression on both cylinders? What is it.
