Seachoice Streamlined Shaft Anode with Allen Screw – 2" (Model X9), Magnesium | Freshwater
The Seachoice Streamlined Shaft Anode is a single-piece sacrificial anode designed to protect propeller shafts from galvanic corrosion in freshwater environments. The streamlined profile reduces drag compared to traditional cylindrical shaft anodes, and the included Allen screw provides a secure, tool-assisted installation directly onto the shaft.
Magnesium is the correct anode material for freshwater use — it is more electrochemically active than aluminum or zinc in low-conductivity freshwater, providing effective galvanic protection where other anode materials may be too passive. This 2” model (X9) is sized for larger propeller shafts and provides more anode mass for extended protection between replacements.
Key Features
- Streamlined profile reduces drag compared to cylindrical shaft anodes
- Magnesium construction — correct material for freshwater use
- Cadmium-free formulation — higher galvanic protection than zinc
- 2.5x lighter than zinc for reduced rotating mass on the shaft
- Allen screw included for secure, tool-assisted installation
- Ideal for aluminum hulls and freshwater vessels
- 2” shaft size (Model X9)
Compatible Applications
- 2” propeller shafts on inboard and shaft-drive vessels
- Freshwater lakes, rivers, and inland waterways
- Aluminum-hulled vessels requiring magnesium anodes
- Any freshwater vessel where shaft corrosion protection is needed
Parts Desk Insights
The Seachoice Streamlined Shaft Anode is the right choice for freshwater inboard and shaft-drive boat owners who want a low-drag, easy-to-install shaft anode sized for a 2” shaft. The streamlined shape is a meaningful upgrade over a standard cylindrical anode — it reduces turbulence and drag at the shaft, which matters on vessels where shaft efficiency is a priority. Magnesium is essential for freshwater use; aluminum or zinc anodes in freshwater may not corrode fast enough to provide adequate protection. For smaller shaft sizes, see the Seachoice Streamlined Shaft Anode – 1¼” (Model X5), Magnesium and 1½” (Model X7), Magnesium.
