  • Visual indicating plug for outboard marine engines
    Patent number: 4789363
    Abstract: A transparent drain plug for the submersible transmission case of an outboard marine engine. The transparency of the plug permits the lubricating oil in the transmission to be viewed to determine by its color whether and to what extent water has seeped into the transmission. The plug has a special configuration which provides it with a lens effect to enhance the visibility of the transmission case interior.
