Milky outdrive oil Volvo-Penta

[jflongwell]

My DP's outdrive oil is milky, but is still pretty viscous. I believe the problem is the seal for the shifter. Any thoughts as to how much damage was done to the gears?

I have had this same problem. I think its just a drop or 2 of water that gets in on the filler plug.

In over 2 years I have had no problem because of it though.

Definitely water leakage. Check all seal points. Unless it ran or sat for a long time with the water in, there's a good chance there is no damage. Drain and refill, watch carefully, and after the next time (now or next summer) you run the boat, take a clear container and drain some oil from the lower unit into it to check for water. No more water means you should be OK.

You need to do a pressure and vacuum test. If it fails, put the whole drive in a water tank and see where the air bubbles come out under pressure. Ideally, you should change all the seals.

Where would you input the air? Possibly the top where the dip stick goes in?
Great idea!
I am planning to change the shift seal and see what happens.
Thanks

From the top works fine. Use a hand pump or a compressor with a regulator for no more than 10PSI
