Caldwell Casting C0750A 3/4" Streamlined Shaft Anode - Aluminum

The Caldwell Casting C0750A is a streamlined aluminum shaft anode designed to provide superior corrosion protection for 3/4" propeller shafts on inboard and sterndrive marine vessels. This barrel-style collar anode installs directly on the prop shaft to protect against galvanic corrosion in all water types.

Key Features:

• Constructed from Navalloy aluminum alloy manufactured to military specification MIL-DTL-24779
• Two-piece clamp-on design with interlocking halves for easy installation without removing the propeller
• Stainless steel hardware included - nuts pressed into casting and bolts captured with plastic retaining washers
• Red spot wear indicator shows when anode needs replacement
• Streamlined barrel shape minimizes turbulence and drag
• Suitable for salt water, brackish water, and fresh water applications
• Fits 3/4" diameter shafts

Performance Metals aluminum anodes are more active than zinc anodes, providing enhanced self-cleaning performance and making them an excellent choice for vessels operating in salt or brackish water environments. The aluminum-indium alloy composition delivers reliable cathodic protection to extend the life of your underwater metal components.
