Gear box oil mariner 40 2 stroke

[popeyethesailor]

Just drained my gear box oil and it looks like this,

It was cold and had been sitting there for a long time, I have no idea when it was last changed, the washers did not look the best to me,
After I mix it up it looks like this


Is this normal or is there water in there?

Thanks Stuart

If you have water ingression, and its quicksilver gear oil used it will go milky white.it looks normal from the pictures I can see. If there had been water in the oil and it was left standing for a long time usually the water and the oil seperates and when you drain the g/housing the water comes out first.

Thanks for that, it was odd the two colour oil coming out one was silver.
I have put the oil in a bottle to see if it separates with some heat,
Latest prob is trying to separate the gear housing it's a little stuck!!

I wouldn't say that's normal. If its opaque then it should be black not creamy.

Gear box oil should either be clear or black (if old). I would say your seals have gone.

i checked mine and it was a very dark colour but still clearish.

Gear oil should not go black. Black indicates carbon (engine lube oil gets carbon from the combustion cycle, which is why it goes to black.) Gear oil should ideally be amber; may be a bit cloudy from metal particles or other contaminants, but not milky like chocolate milk.

If you still have to old oil, pour it into a clear container and let it settle - if water pools in the bottom, you know what's causing the cloudiness. Then it's a matter of finding out how it got in.

That looks like typical 'mayonaise' to me, ie oil and water mixed together.
