I have an 1988 Mercruiser Alpha One MR. I have resealed the upper and lower short of the prop shaft seal and seal on the shaft of the ujoint. When I pressure tested, I sprayed soapy water on these seals and did not see bubbles. I've pressure tested (held 14 psi for 2 days) and vacuum (6" mercury for 24 hours) with the unit empty of oil. Yes I also turned the shaft by hand when testing. haahve made sure I put the washer in when assembling the upper and lower. After a couple of hours on the water I had the oil turn a light tan color in the aftermarket oil addition reservior. Could it be this is not water but is just aerated oil instead? I am at a loss on this one, is there anything else that I could be missing here?
