I am getting ready to launch for the season here in NY. I drained the oil in my outdrive and it was cloudy milky. Clearly water. I put the oil in a clear container to see how much. Although there is some cloudyness in the bottom of the container (2 inches) . There is no actual separation of water and oil. From what i am understanding, it does not take too much water to cause the oil to become very cloudy.
I pressurized the stern to 15lbs and found leakage at the top cover where the dipstick is. I removed the cover and found some corrosion around the gasket. I cleaned everything up quite well and put it all back together. I then repressurized it and it held 15lbs for several hours. I then pulled a vacuum to 15". It did not hold but dropped to about 9" and then held. I know from my years working in refrigeration that moisture will cause this to not hold a good vacuum. Since it was holding at 9, i thought i would go ahead and fill it. ( i have to take the boat out again in about a month to have it bottom painted so i can check it then to see if there is water getting in).
Now, i put water into the flush connection and started it up. I am getting water from the stern drive exhaust which is clearly ok. From around the props which i believe is normal as well. From the exhaust bellow (a problem), and from under the sterndrive where the bottom anode is mounted. (im not sure if this is normal)
Can anyone give me any insight on all of this?
