I went to change the lower unit gear lube in my Johnson and found the lube to be milky. I went to my dealer and bought a new prop seal thinking water must be coming past that. After removing the prop there shows no sign of oil on that seal. I pulled lower unit (which is a pain) and did not see anything that looked oily around or under water pump. Is there somthing I'm missing. Any advise will be greatly welcomed.<br /><br />thanks
