I have a 6hp wards sea king. The model is tag is missing but the best I can tell it is a 1972(ish). I got it last fall and finally got it started. Warmed up and ran great. The water pump was working well and everything ran fine. After I ran it I checked the oil in the lower unit and had water come out and a little oil. I know I will need to add oil but am not sure of what kind since I don't know the model number. Also, why is water in the oil? Any help would be greatly appreciated. Thanks!
