MARTYR Shaft & Rudder Anode

Streamlined Shaft Anodes / Imperial
Protect your boat, Respect our waters.

Martyr Anodes provide low-cost marine corrosion protection for boats, marine structures, and boat equipment.

Martyr is the only manufacturer that offers all three alloys that protect your boat from corrosion that can occur in salt water, brackish water and fresh water. Our Traditional (Zinc) anode is for use in Salt Water, Premium (Aluminum) anode for use in salt and brackish water, or Fresh (magnesium) anode for use in fresh water. Our marine anodes are made of a specialized alloy based on the US Mil Spec using only high purity metals.


Two stainless steel hardware options to choose from:

• Allen Head
• Slotted head

Both with lock washers & bolt retaining washers that prevent the anode from falling off - easy installation underwater.
