Location: Ames, Iowa | Replacing lower unit lube. The lower unit on 50 hp Evinrude on my wife's boat ( yes, has her own boat) has a middle screw with a gasket on it like the top and the bottom screws, which are the drain and the vent screws. What is the middle screw for? It is between and set back just a bit closer to the prop than the other two. |
