Martyr Anodes Autoprop Propeller Nut Anode with Nylon Insert

The Martyr Anodes Autoprop Propeller Nut Anode (also called an Auto Prop prop nut zinc or sacrificial anode) protects your propeller and drive components from galvanic corrosion. It replaces the standard propeller nut on Autoprop propellers. The anode corrodes first, so your prop and underwater metals last longer.

Key Features:

• Sacrificial zinc anode made for Autoprop propeller nut applications
• Nylon insert helps the nut stay secure on the shaft
• Designed for easy do-it-yourself installation
• Made by Martyr Anodes, a supplier of marine cathodic protection for boats, marine structures and boat equipment
• Built to the latest US military alloy specifications, with chemical testing for consistency

Installation Note: The nylon insert is good for one initial application only. Use a thread locker or Teflon tape to get the best hold. Check the anode regularly and replace it when it has worn down.

Choose the correct variant for your Autoprop model to keep your propeller protected in salt, brackish or fresh water.
