Systems and methods for corrosion protection on marine drives

A corrosion protection system, the system comprising:

• a marine drive for propelling a marine vessel in saltwater, the marine drive comprising a generally planar outer running surface and a collection area located proximate to the outer running surface;
• a source of electricity;
• and
• an electrode that conducts the electricity to the saltwater such that the electricity inhibits corrosion on the outer running surface with a byproduct of chlorine gas bubbles;
• wherein 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;
• and
• a retainer that attaches the electrode to the marine drive, the retainer comprising a retainer perimeter that mates with the marine drive and an outer retainer surface that faces away from the marine drive, wherein the electrode is attached to the outer retainer surface.

A method of preventing corrosion on a marine drive for propelling a marine vessel in saltwater, the marine drive comprising a generally planar outer running surface and a collection area located proximate to the outer running surface, the method comprising:

• conducting electricity to the saltwater via an electrode such that the electricity reacts with the saltwater and generates chlorine gas bubbles that tend to cause corrosion on the outer running surfaces;
• inhibiting flow of the chlorine gas bubbles towards the collection area by orienting the electrode on the marine drive so that the electrode protrudes out from the outer running surface and faces away from the collection area;
• selecting an angle at which the electrode is mounted with respect to the outer running surface so that the chlorine gas bubbles are directed away from the collection area at least when the marine vessel is stationary;
• and
• providing a baffle between the electrode and the collection area and selecting a height of the baffle so as to inhibit a flow of chlorine gas bubbles to the collection area at least when the marine vessel is stationary.
