- Description
The MARTYR Walt (Walter) Keelcool Anode 6-3/4" × 1-1/4" (Aluminium) is a specialized sacrificial anode designed to protect Walter keel cooler systems and associated marine engine cooling components from galvanic corrosion. Engineered for durability and performance, this anode ensures reliable protection in saltwater and brackish environments.
According to MARTYR, keel cooler anodes are designed to install under the mounting feet or along the cooling system, providing direct protection to critical cooling hardware exposed to seawater.
Manufactured from high-purity aluminum alloy, this anode offers superior efficiency compared to zinc, delivering longer life, lighter weight, and improved protection performance.
