Martyr Anodes Limited Clearance Shaft Anode with Stainless Steel Allen Head Zinc Anodes/Zincs

The Martyr Anodes Limited Clearance Shaft Anode is a zinc propeller shaft anode (shaft zinc) that protects your boat's underwater metals from galvanic corrosion. It is built for shafts with tight clearance. Its low-profile design fits in spaces where a standard shaft anode will not. It attaches with a stainless steel Allen head screw.

Key Features:

• Limited clearance profile: a compact design for tight spaces along the propeller shaft
• Zinc construction: sacrificial zinc corrodes in place of your shaft, propeller and other submerged metal parts
• Stainless steel Allen head screw: secures the anode to the shaft
• Multiple sizes: available to match different shaft diameters, so you can choose the right fit
• Martyr Anodes quality: from a brand known for marine sacrificial anodes

Check your anode regularly and replace it once it has worn down. Doing so keeps your shaft, propeller and running gear protected. Select the size that matches your shaft from the options on this page.
