Hot outboard

I ran my newly purchased 15hp Johnson 1999 2 stroke today and I noticed that the leg of the outboard got pretty hot.

Water was coming out the tell tale as it should so I assume the cooling is ok but should the leg get hot? Or is there something wrong?
Thanks

Not much in the leg apart from a shaft down to the gearbox, have you checked the oil in the gearbox.

However there is the exhaust so that could be what's making it feel warm

Had it been the 4 stroke I'd expect the leg to be warm from the oil pan but no a 2 stroke shouldn't be "hot" to touch on its leg.

How hot are we talking ? Was the pumping water warm too ?

Warm fair enough. The exhaust is piped down there, and the cooling water should also exit via the same pipe to keep it cool...

Thanks for all your replies.

I will probably run it again today and will check again.

Is the fuel/oil mix ratio correct?

Hi yes it's run at 50:1 which is what the seller and the manual says it should be.

Update.
I've just had a chance to run the OB and the leg is hot after a short period of the OB running.
The tell tale is cool but the leg is probably about the same temperature as a freshly poured cup of tea. Bearable to touch for a short time if that make sense.
Hope someone can help with this or tell me if I'm worrying over nothing.
The OB is a 1999 Johnson J15REEA.

It's, normal, the leg is meant to cool from being immersed in water. The exhaust can make it quite hot to touch. I often see steam coming off mine
