I set out to replace my impeller today. While getting all my crap together to do the job I saw this. The motor is a 2 smoke Johnson. So is this normal or should I be worried?

thats all good. the small hole lets water out of your exhaust housing when the motor is tilted. the other is from the exhaust through the hub.

It would be a good time to run some seafoam or ring free through your motor, looks like you do have some unburned oil build up.

Running a 2 stroke at idle speed produces the least complete burn.
As a result, all the unburnt gas and oil are deposited in the exhaust housing.
After a trip, or flush, all those deposits drain down to the relief hole
and thru-hub exhaust port and leak out.
That's a good reason to keep an old carpet chunk under your outboard
when it's stored in the garage. To catch the drips and prevent oil stains on your concrete.
