I changed the foot oil and as I usually do, put it in a container and let it sit for a week to check for any metal, etc in the oil. I've never had water in my oil but this time I have about a half an inch of an off white stuff that settled on the bottom of the container. Is this what water looks like in foot oil?
If it was white or milky then it's water, when you drain your lower unit, if you watch. the water will come out first. time to do a pressure test and find the leak.
First after a day on the water, I could drain out a cup of clear water before good oil came out.
I would top it off (not more than what good oil came out the drain) with someGL-5 spec gear oil per the Seloc manual for Johnsons.
But after topping it off five or six times, the water would no longer settle out. It remained milk shake so I replaced all the oil with new stuff until I get around to replacing seals.
Is there a difference between GL-5 spec oil andGL-5 spec oil with "marine use" on the label other than price?
Or maybe there was synthetic oil in the foot when the water would still seperate?
