Johnson sea horse lower unit leak.

[lewis7896]

1970 johnson 25hp is leaking a small amt of oil from the area where the lower and upper units meet also from a port on the same side as the fill and drain plugs. What could it be?

Sounds like the normal 2-stroke exhaust draining down...

Any water in your lower unit oil ? If not, run it.
