Hello All,

Noticed today that I had a small spot of oil under the lower unit. It appears to be coming out of the water intake. I looked into the intake the best I could and there appears to be oil in the intake.I figure it is most likely a seal or O-ring that is bad. Anybody got any idea which one it would be? If it was one of the seals on the prop shaft I would think the oil would be leaking from the prop area. I think it may be one of the seals between the upper and lower case based off what a I can see on the diagram. Outdrive is an SX-C! on a 97 Larson with 4.3 gl.
