Hot Shaft, Cool(ish) Stream

[A ReelCool Chick]

I just got around to getting her ready for the season. I cranked her up and ran her at idle for about 5 minutes. Pee stream was strong, but something said to touch the water to see how hot it was. Water felt kinda cool, but then I touched the shaft and it was hot...like, count to 5 and it was uncomfortable hot. Steam was coming from it.

Being the noob that I am, I shut it off. I changed the oil when I winterized her. I'm running a '94 Evinrude Ocean Pro 225. Should I be concerned?

As always, thanks in advance for your input!
