This boat is my nemesis. I think I have 4 active posts with this boat as each time something is fixed, another issue comes up

On to the details

I have a 95 Larson with a 5.7 liter mercruiser where the out drive is leaking gear oil and taking in water. The out drive has been painted so I am not sure how to tell what model it is. How I noticed this is I took the boat out on the lake last weekend for maybe 2 hours and prior to launching I topped off the gear oil reservoir which appeared to normal consistency and color. When I returned, the oil in the reservoir was a milky color. After that, I had the boat sitting in my driveway for two days and noticed the drive consistently leaking the gear oil. It appeared to have drained about half the oil in the reservoir in two days. Looking for some help on diagnosing and fixing the issue. Also, how would I completely drain the drive oil? I cant seem to locate a drain plug. Below are a couple pictures of the leak and a couple of a disconnected hose in the outdrive that I am not sure what purpose it serves . I appreciate the help

Re: Mercruiser out drive leaking gear oil and taking in water

Took it out again today and put fresh gear oil in. By the time I came back it was a milky color again. I am pretty sure I can tell where its leaking out; would this be the same place it is taking on water? Also, Where would I be able to completely drain this out drive?
