Talamex Shaft Collar Anode — Flat Profile | 4Boats

Talamex flat-profile shaft collar sacrificial anode for galvanic protection of propeller shafts and collar fittings. Designed for even wear and simple fitting to reduce corrosion risk.

• Materials: available in zinc, aluminium and magnesium. Zinc and aluminium are commonly used for saltwater and brackish environments; magnesium is suitable for fresh water. Choose alloy based on your operating water type.
• Design and fitment: two-piece flat clamp-on collar that provides even sacrificial wear. Supplied with stainless clamp bolts and nuts; check the product size listing for exact bolt specification.
• Compatibility: measure shaft diameter across the journal area and select the matching collar size. Typical commercial sizes cover small hobby shafts up to larger prop shafts—see the product size chart for available shaft diameters and outer dimensions.
• Installation guidance: clean shaft to bare metal to ensure electrical contact, fit the two halves evenly and tighten bolts incrementally and uniformly to avoid distortion. Use appropriate torque for the bolt size and avoid over-tightening; use stainless fasteners and anti-seize if required.
• Maintenance: inspect at each haul-out or at least annually. Replace the anode when it is significantly consumed (commonly around 50% loss) or if mechanical damage occurs. Verify continued electrical continuity between anode and protected metal.
• Standards and verification: anode alloy and manufacturing details vary by item—consult the product label or datasheet for exact alloy specification and any applicable standards or certifications.
• Compatibility notes: confirm shaft material and diameter before fitting; avoid insulating coatings between anode and shaft and ensure the anode material is appropriate for your water type to prevent unintended galvanic effects. Do not paint anodes and avoid mixing different anode materials on the same vessel.
