Abstract
Several embodiments of reference electrode constructions for use in electrically anti-corrosion protection systems for marine outboard drives. In each embodiment the reference electrode is contained within a protective covering with a restricted small volume area surrounding the reference electrode. As a result, when the reference electrode dissolves in the body of water in which it is operating it will form a saturated solution in this small volume area to preclude further dissolution.
