Seachoice Streamlined Shaft Anode Aluminum Model

The Seachoice Streamlined Shaft Anode is an aluminum sacrificial anode (also called a prop shaft zinc alternative or shaft collar anode). It helps protect your boat's propeller shaft and nearby underwater metals from galvanic corrosion. The streamlined barrel-collar profile mounts on the shaft and is secured with an Allen screw.

Key Features:

• Aluminum construction suited to salt and brackish water use
• Cadmium-free, environmentally friendly formulation
• Higher protection than zinc
• About 2.5 times lighter than zinc
• Corrodes less than zinc, so it lasts longer
• Well suited to aluminum hulls
• Installation hardware included

Replace the anode when it has largely corroded away so that your shaft and underwater hardware stay protected. Check the child item listings below to choose the right size for your shaft.
