2008 150 ho 4 stroke Yamaha outboard

I just launched my boat for the season, i got it from the launch to the cottage 1 mile and the boat shut down. I tried to restart it but it would not idle. Then the alarm went off so I shut it down. I opened the cowling and noticed oil all over the engine. I also notice when I got back the cottage that there was no water coming out of the side tube and the engine was very hot Can anyone tell me how bad this is, expect the worst and hope for the best.

No. Do a leakdown test on the cylinders.

Could it be that I have an air lock and oil got into the crank case. When I filled the oil I don't think that I pulled out the dip stick when I topped up the oil. Will this damage the engine?? Thanks in advance.
