I have a 50hp Johnson that leaks oil onto the skeg. It has done this the last two seasons since I bought this motor.<br />Could this be unburn fuel and oil from the VRO?<br /><br />I have seen another Johnson 50hp same year (2001) that was doing the same thing.

Re: oil leak

You need to determine whether it is residual two cycle oil or gearcase lube.If it looks thin and black it is likely just two cycle residue.If it appears thick and milky it is likely lower unit oil.I would remove the lower unit drain plug and see what weeps out.If it appears milky you likely have a seal leak.Otherwise,next time you service the waterpump,replace the inner exhaust housing gaskets.This is sometimes a source for two cycle oil buildup within the mid section cavity.
