I unwrapped my boat today for the first time all year. The first thing I did was change the lower unit oil. I drained the old stuff out and put some brand new stuff in. I barely used the boat the last few years so the oil that came out was super clean. I filled up the new stuff and I'm on my way.
Then when I'm trying to start the engine, I notice something is dripping out. There's a little hole that I guess is some kind of vent hole? Except it's well below the water line so seems like that vent would become a water inlet? What is leaking out? Whatever is leaking out is filthy! Is there some OTHER kind of fluid/oil in the lower unit besides the primary gear oil?
What do you think?
The motor is a 1989 Mercury 90HP 3-cylinder outboard.
For all it's flaws and age, with a new battery and a full tank of gas, it did start right up I didn't make it to the water yet though. Soon, hopefully.
