Abstract
A marine vessel propulsion device having a metal component in contact with water. The marine vessel propulsion device includes an anticorrosive anode made of a metal material that is less corrosion-resistant than the metal component, is electrically connected to the metal component, and is disposed in contact with the water contacting the metal component, a primary reference electrode isolated from the metal component and the anticorrosive anode, and disposed in contact with the water contacting the metal component, and a potentiometer that detects a potential difference of the metal component or the anticorrosive anode with respect to the primary reference electrode.
