Aluminum Hull Anode CMT-ZHC2AA

The CMT-ZHC2AA is a marine-grade aluminum hull anode designed to protect hull-mounted metal components from galvanic corrosion. Engineered for long-lasting performance, this anode sacrifices itself to prevent damage to critical underwater metals such as trim tabs, thru-hulls, shafts, and other bonded components.

Aluminum anodes provide superior performance across saltwater and brackish environments, offering longer life and more consistent protection compared to traditional zinc.

Key Features

• Genuine OEM-style aluminum hull anode
• Marine-grade aluminum alloy construction
• Designed for hull-mounted corrosion protection
• Performs in saltwater and brackish water
• Longer lifespan vs zinc anodes
• Direct replacement for standard hull anode applications

Application / Compatibility

Used on:

• Boat hulls (externally mounted)
• Trim tabs
• Thru-hull fittings
• Bonded underwater metal systems

Common on inboard, sterndrive, and larger vessels
Suitable for boats operating in mixed water conditions

Serial Number / Fitment Notice

Hull anodes vary by:

• Mounting hole spacing
• Size and profile
• Vessel bonding system

Always confirm dimensions and mounting pattern before ordering.

When This Part Needs Replacement

• Anode is 50% or more consumed
• Heavy pitting or uneven wear
• Loss of bonding/contact
• Seasonal maintenance or haul-out

Installation Notes

• Ensure clean metal-to-metal contact with hull
• Do not paint the anode surface
• Mount securely using proper fasteners
• Check bonding system if uneven corrosion occurs

Alternate / Cross-Reference Part Numbers

• Camp Company: CMT-ZHC2AA
• Zinc equivalent: CMT-ZHC2AZ
• Magnesium version available for freshwater applications

Parts Desk Insight

Aluminum hull anodes are now the preferred choice over zinc for most boats. They offer better efficiency and longevityespecially important for boats that move between salt and brackish water environments.
