Okay, stored the boat for the winter with the drive down in a dry garage with cover on. Picked boat up and ran drive up and drove 150 miles. Just checking the fluid in trim pump for normal maintenance I noticed the fluid was all milkshake. Now I was pretty sure the oil looked fine all last season but there is a chance it had water in it from it being swamped the year before I bought it due to a leaky bellows.
So I figured I'd just pull the reservoir and clean it out, flush the lines and cylinders using the method in the Mercruiser manual which I followed to a T and had clean oil (I'm using 10w30) coming out the lines and ran drive up and down part way a few time to flush residual fluid in cylinders until they where nice and clear. So last step was to run drive all the way up and down a few times to get air out of lines and guess what, yep my reservoir once again looks like a milkshake.
What gives? Is it from the air bleeding out? I did one time when flushing it out run it just a tad low and it sucked air for a millisecond. So if it is just air will it return to the oil state or do I need to start over?
