I’m doing maintenance on my 2004 90 hp Mercury 2 stroke,I’m changing lower unit fluid,my lower unit has to screws and one on very bottom, the top two one on left is vent/right says fill bottom is drain.can someone pls explain how to fill lower unit the right way I’m getting mixed info, and I’m hoping to get help here pls
 
You have two screws on the same side. After draining you will fill from the bottom hole until it cleanly comes out the top. Don’t remove the fill from the bottom hole until you put the top screw in. Then quickly remove filler and replace lower screw. Here’s a video that will help. https://youtu.be/YCUJbR1MEJA
