CMP CMX04AL Streamlined Aluminum Shaft Anode 1-1/8" ID x 2.36" OD x 2-1/4" H

The CMP CMX04AL is a streamlined aluminum shaft and rudder anode engineered for corrosion protection in salt and brackish water environments. Aluminum anodes are the ideal choice for brackish and saltwater applications, offering superior galvanic protection compared to zinc in mixed or low-conductivity salt water conditions.

Key Features:

• Material: Aluminum alloy — ideal for salt and brackish water use
• Inner Diameter: 1-1/8 inch — fits standard 1-1/8" propeller shafts
• Outer Diameter: 2.36 inches
• Height: 2-1/4 inches
• Interlocking halves design for easy installation and secure fit on the shaft
• Streamlined profile reduces drag and turbulence for improved performance underway
• Designed for use as a shaft or rudder anode

The interlocking two-piece construction allows the anode to be installed or replaced without removing the shaft, making maintenance straightforward. The streamlined shape minimizes water resistance while maximizing sacrificial surface area, helping to protect your vessel's underwater metals from galvanic corrosion throughout the boating season.
