And Mac the fluid has been sitting for over an hour, no water at all

Just went out and checked fluid again, no water at all, and there is a white washer on the top screw could not see it before but there is none on the bottom. Is there supposed to be one there to?

I don't know if they all have the little washers - but my Johnson/Evinrude motors all had em.

That's wierd that its so white?? I've never seen it look that way! Only whitish swirly looking, you know?

It must have a heck of a lot of water in it or something??

Yes, both screws had the washer. 3 different motors I've owned. The oldest was a 1975 and the newest a 1991. I don't know if the newer ones still had the washer. But......I bet tha Skool man can school us on that!

Yea they do Blue I just got a diagram for it and both have those washers, only the upper one is on my motor, I'm wondering if that is why water got it, assuming that is what it is. Because like you said when I've seen water in a lower unit before the oil was dark with some whitish swirls in it. This is solid colored with absolutely no black at all and it feels like oil and there is no water seperating from it at all ???

Just got off the phone with a good friend of mine, older fellow been building and working on outboards for a long time. I told him what I found and he told me he has seen that several times in past, could be a leaking seal, could be since the blue washer that goes on first in the bottom screw was not put on last time it was opened it could have drwn water from there. But he says that if I had that kind of problem there would have been quite a bit of visible water in the oil which as of now (4 hrs) there is a table spoon worth he says he has seen it with very old oil that has not been changed for a long time and he has seen it when cheap oils were used and not changed and he has seen it when additives have been put in the oil. He told me to pick up the washers and replace and put new oil in and run it a couple of times then change it again. Look for water and go from there.

If its water, *it will separate. *My 40HP Suzuki had water in the lower unit discovered during the fall drain. *Changed prop seals first because they were easiest to change. *Next year I had water again. *Pulled lower end and changed the shaft seals near water pump. *Result, no water the next year. *I've had four motors and all had washers or seals on the two screws. *Someone in an earlier post had said they changed their lower unit oil twice a season, middle and at the end of the season. *Reason given for mid season change was to catch a leak early before any major sugery was required. I thought it was a great idea but I haven't started the practice yet. *Good Luck! *Bill Mc *;D

Question can you change the water pump impeller and not drain the fluid, Rich had said the pump had been done and it pumps like a fire house, but that fluid definetly has not been changed for a long time ???
