The Martyr 1 Inch Streamlined Shaft Anode - Aluminum is designed to help protect your inboard prop shaft from galvanic corrosion and stray current damage in saltwater and brackish water. Built for 1 inch diameter shafts, this marine aluminum shaft anode offers dependable cathodic protection while its streamlined shape helps reduce drag compared with bulkier designs. For boat owners who want reliable underwater protection without complicated installation, Martyr delivers a durable, purpose-built solution.

Key Features

  • Aluminum Construction: High-purity aluminum alloy is suited for saltwater and brackish water applications where corrosion control is critical.
  • 1 Inch Shaft Fit: Designed to clamp securely onto a 1 inch prop shaft for inboard boat protection.
  • Streamlined Two-Piece Design: Interlocking halves, Allen head bolts, and retaining washers support full shaft contact and secure installation.

Martyr anodes are a trusted choice for boat maintenance because they help extend the service life of running gear exposed to harsh marine conditions. This streamlined shaft anode is a practical replacement for worn anodes on inboard boats and is ideal for routine preventative maintenance. The aluminum finish matches the intended alloy type and use case rather than decorative styling, giving you effective protection where it matters most.

Approximate anode dimensions listed by retailers are 2 1/8 inches outside diameter and 2 1/8 inches in length. Martyr recommends this style for compatible 1 inch shafts operating in saltwater or brackish water environments.
