Rev Limiter

My wife took a turn plowing some snow yesterday. She loves riding and just wanted to try pushing snow. She got into some deep snow and sort of got stuck.
She tried rocking back and forth and after about 45 minutes was able to free herself.
She would peg the Rev limiter in forward and reverse while trying to get unstuck.
At one point she had the poor thing Rev limited for about 10 minutes straight. The engine was so hot it was smoking. But she just kept whipping it as hard as she could.
My question is, do I have to check the engine out for any sort of damage?
It sounds a little different now and runs a little rough.

New to forum in North Carolina

Been riding bikes for 55 yrs. After my 4th stroke decided to sell my 5 bikes and take up 4 wheeling. Bought a 2010 Sportsman 500 with 110 hours. I used to race dirt bikes and guess it made the change much easier. This thing is a blast. We recently had 14" of snow and this thing went with no problem, scared a few cows on the neighbors 100 acre farm. Did jump a 6' wide creek but was running to fast to avoid a tree 20' up the bank. Bought a double tube front bumper to limit damage, ride it like I stole it. Got a winch from Cabelas last week, Kolpin 2500 for Under $90 with taxes, 5 yr warranty. Gearing up for 2 weeks at Hatfield McCoy in West Virginia. Tried a few atv's but the polaris is by far the most comfortable ride for this 63 yr old.

Heat question

I'm shopping for my first can am and was wondering about engine heat. At what engine size does heat really become a concern such as plastic warping/etc. Is the 650 not too bad? 570 is plenty of power for me but I'd rather do the 650 because of the suspension changes. If the 570 was getting the suspension changes next year I could probably wait.
