Now I'm trying to change the lower unit oil in this thing. It looks fine, but I think it's about 10 years old. Just wondering if there's any special procedure to do that. On the older motors, I know there's a drain and a vent and you have to fill it up from the bottom, but I can only see one screw to take out, right on the side of the LU behind the prop.
When in doubt, duct tape!
