Yamaha 2.5 hp Not Starting

Hello, I have never used this forum before so please let me know if I should have done something differently regarding this post. The reason I am posting here is because I have a question about a small Yamaha outboard that I recently purchased.

The motor is a 2.5 hp 4-stroke. I got it new, and it only has about 15 hours on it. I followed the manual's break-in instructions and changed the oil and gear lube afterwards.

It's been running ok, but on Saturday I had been using it at full speed for about 25 minutes when I hit something (a log or something) so I used the kill switch to shut it off. Then when I tried to restart it, it would not start at all. Eventually, about an hour later, I got it to start, and then it ran fine back to the dock, but I haven't used it since. Could I have maybe just flooded the engine by killing it while it was hot, or could there be some other problem?

Initially when it would not start, I started cranking the heck out of trying to get it to start. I later read that it's not good to crank a motor more than a couple times every two minutes or it could cause some sort of damage. Is that true? Can you damage a motor by cranking it like a mad man?

Thanks to anyone who can give some advice!

Did the motor flip up when you hit the log? That will send the sump oil and fuel in the carb everywhere and it can take a while to settle again. I wouldn't worry too much about it if no physical damaged to the leg or bracket occurred.

Lots of cranking can overheat the starter motor, but isn't really a problem for the motor itself provided it has oil.

Yes, it definitely did flip up. I think it actually locked into the upright position, which it why I killed it immediately. Good to know that was most likely the problem.

Thanks for answering!
