Parts Desk Insights
This is the saltwater zinc variant of the small block trim tab anode for smaller Yamaha outboards — the standard choice when only the trim tab position needs replacement and the other lower unit anodes are still serviceable. Zinc is the traditional anode material for saltwater use. If you prefer aluminum for its superior electrochemical activity in saltwater or brackish water, see the aluminum version: Martyr CM6E04525111A Yamaha Small Block Trim Tab Anode, Aluminum. If you operate in freshwater, a magnesium anode would be required instead. For the larger Yamaha trim tab anode, see the Martyr CM6AW4525100A Yamaha Trim Tab Anode, Aluminum. For other Yamaha individual anodes, see the Martyr CM61A4537100A Yamaha Skeg Anode, Aluminum, Martyr CM6644537101A Yamaha Skeg Anode, Aluminum, Martyr CM6884537102A Yamaha Skeg Anode, Aluminum, Martyr CM6E54537101A Yamaha Skeg Anode, Aluminum, and Martyr CM68V1132501A Yamaha Internal Anode, Aluminum.
