Choosing the correct anode
Freshwater only. Follow the equipment manufacturer's requirements for anode material and application. A shared engine brand or similar appearance alone does not establish compatibility.
View Martyr's product specifications and drawing. Browse Martyr anodes and kits.
Inspection and replacement
Inspect regularly and replace when approximately half of the anode has been consumed. Keep the anode unpainted and ensure clean, secure electrical contact with the protected metal. Follow the equipment manufacturer's installation instructions.
