Lewmar sacrificial anode kits provide essential galvanic corrosion protection for TT series bow thruster shafts and components in marine environments. These zinc anodes are model-specific replacements that sacrificially corrode to protect stainless steel shafts, propellers, and gear housings from electrolytic damage. Regular inspection and replacement extends thruster lifespan and maintains optimal performance, with each kit designed for precise fitment on the corresponding thruster model.
