MARTYR Aluminum Rudder & Trim Tab Anode Pair 0.35×1.87 Inch Bolt

Description

Product Overview

The MARTYR Aluminum Rudder & Trim Tab Anode Pair is engineered for marine vessels operating in salt and brackish water. Crafted from high‑grade aluminum alloy, each anode measures 0.35″ x 1.87″ x 0.20″ and features a fully threaded stainless steel bolt with a flat washer for a secure, vibration‑resistant fit. The exterior finish combines stainless steel and zinc plating, delivering superior corrosion resistance and a Grade A rating.

Usage

These anodes are designed for installation on rudders and trim tabs of recreational boats, fishing vessels, and small commercial craft. They perform optimally in mixed‑water environments where traditional zinc anodes corrode quickly. The compact size fits standard groove diameters of 1.88 inches, making retrofitting simple for both new builds and replacement projects.

FAQ

Can these anodes be used in freshwater?

Yes, they work in freshwater but provide the greatest benefit in salt and brackish water where corrosion rates are higher.

Do I need special tools to install the bolt?

The bolt uses an Allen (hex) head, so a standard 5 mm hex key is sufficient for installation.

How often should I replace the anodes?

Replacement intervals depend on water conditions, but most users find they last twice as long as standard zinc anodes, typically 2‑3 years in harsh saltwater.

Are the anodes compatible with all rudder sizes?

They fit groove diameters of 1.88 inches, which covers the majority of small to medium‑size recreational boats.

What warranty does MARTYR provide?

MARTYR offers a one‑year limited warranty covering material defects and manufacturing errors.
