The engin oil is fine. It's the gear oil in the lower unitYou have gear oil in The lower unit and you have engine oil in the motor. Both can get milky if water is entering and your engine exhausts through the prop meaning what you are seeing on the lower unit could potentially be either. Its not easy to tell from your explanation which oil is getting milky that you have noticed. You need to check the oil in both for condition. There is a large faced screw on the bottom side of the lower unit (Fill) that you can unscrew and check for water or contaminated oil, hold a clear glass jar under this to capture oil for inspection. On the motor you can check the dipstick under the cowling for the condition of the oil. Once you narrow it down we can help determine what remedies may be available to you. Do not run your engine in its current state as you risk causing catastrophic (read expensive) damage. It might be as simple as removing some old tangled fishing line or it might be very much worse, we are here to help you figure that out.
when I transported it I had to lay it on its side (I made sure it was the right side) when I got home white ,grayish colored oil was coming out of a small hole on the lower unitBy the way, if it does come to replacing seals then it is something a mechanically minded person can do but if that's not you then take it to an outboard shop and have them replace the faulty seal and check the condition of the other seals (replace as necessary). Then they should do a pressure test (and possibly a vacuum test). The parts are not expensive and it should be 1-2 hours work.
