Seachoice 95609 Aluminum Rudder & Trim Tab Anode 5" Diameter Model R4

The Seachoice 95609 Model R4 aluminum rudder and trim tab anode provides superior corrosion protection for boats operating in salt and brackish water environments. This high-quality, cadmium-free anode is specifically designed for aluminum hulls and offers enhanced performance characteristics compared to traditional zinc anodes.

Key Features:

• 5-inch diameter x 5/8-inch aluminum anode optimized for rudders and trim tabs
• Provides higher galvanic protection than zinc anodes
• 2.5 times lighter than equivalent zinc anodes for reduced weight
• Corrodes at a slower rate than zinc, extending service intervals
• Cadmium-free construction meets environmental standards
• Ideal for aluminum hull applications where zinc can cause galvanic incompatibility
• Includes Allen screw installation hardware for secure mounting

Aluminum anodes are the preferred choice for saltwater and brackish water applications on aluminum boats, providing reliable sacrificial protection against galvanic corrosion while being compatible with aluminum hull materials. Regular inspection and replacement of sacrificial anodes is essential for protecting underwater metal components.
