Hi, I could use some help. I have a 1986 115 hp mercury outboard with a oil leak in the lower unit. I have put pressure 5+ psi on it through the oil fill port. I find the leak coming out the speedometer hose. I suppose I kneed to rebuild the unit just thought I would see if I am the only one to experience this. I found that I had a problem when I came out of the water and milky looking water/oil is dripping out the little hole that is in the lower unit for speedometer.
