Parts Desk Insights
This is a single zinc anode for the 397768 position — the right choice when only this position needs replacement and the other lower unit anodes are still serviceable. At approximately 0.6 lb., this is a mid-size anode providing solid service life between replacements. Zinc is the standard choice for saltwater use; if you prefer aluminum for its superior electrochemical activity in saltwater, check if an aluminum variant is available for this position. If you operate in freshwater, a magnesium anode would be required instead. For other BRP/OMC/Johnson/Evinrude individual anodes, see the Martyr CM393023A (Aluminum), Martyr CM393023M (Magnesium), Martyr CM393023Z (Zinc), Martyr CM123009Z (Zinc), Martyr 398331 Anode, Martyr 5007089 Anode, Martyr 984513 Anode, and Martyr 984547 Anode.
