Every two stroke I have seen you mix the oil with the gas in the proper ratio. There should not be any oil to change like you would on a four stroke.

You are correct what I was seeing was what I thought was a oil leak. And my brain went in to dam I’m going to blow my engine I found that there was a loose case bolt on the bottom  I have tighten it up and that should solve my issue  and hopefully I won’t have any more brain farts thank you for your information

I should have said outboards as old as yours since the newer ones have a separate oil tank and oil injection systems.
