The lower unit on a boat converts the power of your outboard’s engine to rotation of the prop shaft, which moves the propeller, which moves your boat. Without it, you go nowhere. Its internal mechanical workings put tremendous pressure on the lubricant inside.
This hardworking device just needs some simple, regular maintenance to help it stay that way.
