Martyr Imperial Streamlined Shaft Sacrificial Anode Item # 871849
Description
Features:
- Anodes must be replaced when they are 70% eroded
- Martyr (Martyr 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
- Martyr 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)
Note: Oversized version of anodes have a larger outer diameter than their non oversized counterpart.

Easy to install anode for fresh water sailing.
I need a magnesium anode since I'm on a fresh water lake, and this fit the boat's shaft perfectly. Easy to install.

Appears good & price & delivery good.
This shaft zinc looks good, and the price and delivery were good. We have not had a chance to replace the old one on the boat shaft and wait to see the results of it's protection.
