I was installing a new bilge pump today and when I was through I notice a puddle of oil under my lower unit[crying].
I isolated the leak pretty quick, but for the life of me, I'm not sure what it is. I have 1981 Johnson 50HP, that I think has a 1982+ lower unit on it. I just bought a couple of months ago. Anyway, this is what the schematic looks like
But this is what the lower looks like, notice the hole I have circle in orange, that is where the oil seems to be seeping from. I can't see any threads in the hole but it goes back a little ways. It definitively isn't a hole I knocked in it, somehow. However, none of the schematics I look at have this hole [confused]. Is this the pinon bearing retaining screw or what, #3 on schematic?
Any help is greatly appreciated.
