Vetus Spare Zinc Anode Set f/Bow Thruster

The Vetus Spare Zinc Anode Set for Bow Thruster is an essential maintenance component for marine propulsion systems operating in saltwater environments. Designed for 125, 130, and 160 kgf bow thrusters, this spare anode set protects your thruster's internal components from corrosion and galvanic degradation—a critical concern for any vessel owner who relies on reliable maneuvering control. Whether you're maintaining a cabin cruiser, trawler, or commercial workboat, keeping spare zinc anodes on hand ensures you're never stranded with a compromised thruster system.

Zinc anodes function as sacrificial corrosion barriers, ionizing preferentially before your thruster's propeller hub and internal metallic structures can oxidize. This electrochemical protection is non-negotiable in saltwater service, where galvanic attack accelerates dramatically. The Vetus set mounts directly to the propeller hub center and comes complete with a cap head Allen screw for secure installation—no additional fasteners or modification required. The compact dimensions (4 x 2 x 5 inches) and lightweight construction (0.95 lbs) make it easy to stow aboard as a backup component, ensuring you can perform field replacement without specialized tools or extended downtime.

This spare set is ideal for fleet operators, commercial vessel captains, and weekend cruisers who operate in brackish or saltwater conditions where anode depletion is accelerated. Preventive anode replacement extends thruster lifespan and prevents catastrophic corrosion that can lock up the propeller mechanism. Compatibility is confirmed for VETUS bow thrusters in the 125–160 kgf thrust range; verify your specific thruster model before ordering to ensure correct fit. Regular inspection and timely anode replacement form the backbone of responsible thruster maintenance and should be part of every seasoned operator's annual service checklist.
