Dan et. al., I have noticed that when I change my lower unit lube on my 50 hp 4 stroke Merc before storing for the winter, it is a little cloudy but not like a milk shake. I am planning to have this looked at in the spring when I get the boat ready. Is the normal cause of this an exhaust gasket seal leak? If all worked as intended, should the lube be as clear as when I put it in or does it get cloudy with normal use? I rarely run the boat in the salt and mostly just in the Kenai. Can fresh water also cause internal corrosion?
