Is oil suppose to come out of there?

[Barelyboating]

1970, 60 Evinrude <br /><br />On our last fishing trip we were trolling for sand bass at a very slow speed for about an hour, caught twelve good fish. The next day I noticed oil leaking from the lower unit directly behind the propeller. I had hit a stump while fishing so I feared I bent shaft or busted seal. I detached the lower unit for inspection and found that the oil, (milky yellow white) was coming down the exhaust and did not appear on the upper inner sections of the unit. (i.e, top of the water pump, etc.) I drained the lower unit gear oil and found it to be a blended white/grey color. QUESTION - Can continued slow speeds create a situation where the oil from the gas creates a heavy residue? I never went fast enough to blow it out. Secondly, Does lower unit gear oil turn a milky color after some bit of use? All the seals were replaced last season and the oil was relatively new.<br />Thanks for any suggestions.

Yes residue will form on prop after long runs at low speed. question 2 no way should the lower unit oil be milky at any time, water is getting in there somehow recheck seals as that is about the only place water can get in unless housing was cracked when you hit the stump.

Barely, If your oil in the lower unit is milky, yellow, or white....water is getting in there, and mixing with the oil...Not sure if you mean that oil is comming out lower unit in front of prop (that being nearest to the boat) or through the prop...like a (thru hub exhaust)...maybe you can elaberate.... but always remember that oil should always look like oil, when no water is mixed with it..

It should never be milky. You have a leak in a seal somewhere on the LU. Change your gaskets and the fill and drain plug washers.

My 115hp 82 evinrude has a little oil leaking out by the prop, I store it with the motor down it left a spot about the size of a quarter. it smelt kind of like gas. If I mixed the gas to rich could this be my oil.
