  • Systems and methods for corrosion protection on marine drives
    Patent number: 9168979
    Abstract: Methods and systems are for corrosion protection on marine vessels. A marine drive is for propelling a marine vessel in saltwater. The marine drive includes a generally planar outer running surface and a collection area located proximate to the outer running surface. An electrode conducts electricity from a source of electricity to the saltwater such that the electricity reacts to the saltwater and generates chlorine gas bubbles that tend to cause corrosion on the outer running surface. The electrode is mounted on the marine drive and protrudes out from and at an angle to the outer running surface so as to inhibit flow of the chlorine gas bubbles towards the collection area at least when the marine vessel is stationary.
