Max Prop Universal Sacrificial Zinc Anode – Part No. MP70-U

Protect your Max Prop from galvanic corrosion with the MP70-U Universal Sacrificial Zinc Anode. This 70mm zinc anode is designed for Max Prop applications and is commonly listed for larger shaft sizes, helping protect the propeller hub and related underwater metal components in saltwater use. Universal-style listings describe this size as a zinc anode with an aluminum retaining ring for improved durability and bonding, helping the anode stay secure during service.

Key Features & Specs

• Part number: MP70-U / commonly sold as a 70mm universal Max Prop zinc anode.
• Material: Zinc sacrificial anode for corrosion protection in saltwater applications.

Compatibility / Fitment
Commonly listed for Max Prop 70mm universal applications on boats using:

• 1-1/4 in to 1-3/8 in shaft sizes
• 30mm to 35mm metric shafts
• 50mm mounting-hole centers

Because Max Prop anodes are selected by hub size and mounting dimensions, verify your current anode size, hole spacing, and shaft size before ordering. Max Prop’s own guidance notes that the correct anode can be identified by the “K” dimension, measured between anode hole centers or on the propeller spinner head.

Maintenance Tips
Inspect the anode regularly for wear, cracking, or heavy material loss, especially in saltwater use. Replace it once it is significantly consumed so it can continue protecting the propeller assembly. When installing a replacement, confirm the mounting surfaces are clean and the fasteners are secure to maintain proper electrical contact and corrosion protection.
