CMP CMC09AL Limited Clearance Shaft Anode Aluminum 2" ID x 3.7" OD

The CMP CMC09AL is an aluminum limited clearance shaft anode designed for use in salt and brackish water environments. Engineered for installations where space is restricted around the propeller shaft or rudder, this anode provides reliable galvanic corrosion protection without requiring full shaft removal during installation.

Key Features:

• Material: Aluminum alloy — ideal for salt and brackish water use
• Inner Diameter: 2 inches
• Outer Diameter: 3.7 inches
• Height: 1-3/8 inches
• Interlocking two-piece (clamshell) halves for easy installation over the shaft
• Includes Allen head bolt, lock washer, and retaining washer hardware
• Fits limited clearance shaft and rudder anode applications
• Designed to protect underwater metals from galvanic and electrolytic corrosion

The two-piece interlocking design allows this anode to be installed and replaced without removing the propeller shaft, making it a convenient choice for in-water maintenance. The included Allen head fastener hardware with lock and retaining washers ensures a secure fit throughout the anode's service life.
