Oil in lower unit

[FENIXX3435]

I have a Volvo SP drive attached to AQ131C. I Just changed oil in lower unit.<br />After the third time I go out, Oil is milky? Why only after third time?<br />Is there something that could let water mix with oil? Drain,filler,dipstick were all tight. I trailer it and it sits in same spot in driveway. NO leaks? Thanks for any help.

You need to reseal the unit

I replaced the washers on the plugs. Everything is tight. No visible leaks. It only happens after third day? is there anything else that I can check? The bellows was replaced in Oct last year and clamps are tight.

Re: Oil in lower unit

While you may have changed the bellows, did you check it now to see if there was water in it?<br />Best thing to do is drain the oil and do a pressure test. Then spray all the connections and the shift mechanism under the rear cover with soapy water. The bubbles will tell you whats leaking. If no leaks, try a vacuum test.<br />Could also be a prop shaft seal.<br />Showing after 3 days is probably an accident.
