92 4hp Water in gearcase

[sniffum35]

Hi, thanks for any help in advance.

I have a new to me 1992 4hp outboard. It looks very lightly used. I drained the lower unit and water came out. Not just milky oil, approximately 2-3 ounces of straight up water followed by milky gear oil. When I took the drain screws out the gaskets half crumbled off/half became one with the metal. After scraping the old gasket off and replacing them, I did a pressure test and it holds 10-12 psi without leaking.

Am I safe to assume the drain screws were leaking that much?

If it matters serial is 0A899***

Thanks again.

I usually replace the vertical drive shaft seal as well. Since the motor is that old.

Now you’ve replaced the 2 drain/vent screw gaskets/washers, put fresh oil, go run the motor in fresh water lake or river for a few hours…..then drain the oil and check for water….I’m guessing it’s fixed..
