Martyr Propeller Nut Sacrificial Anode

Features:

• Propeller anodes must be replaced when they are 70% eroded
• Martyr (Canada Metal (Pacific) Limited) only uses mil-spec mil-a-l800l alloy in all of their premium marine anodes
• This alloy helps the anode erode inward giving the anode a sandblasted appearance
• Canada Metal uses a special steel combination fastener that makes it possible to use their Ball drive, which is a hex driver with a universal ball tip (ball-drive is sold separately)
