Zinc Rudder & Shaft Sacrificial Anode — 1-7/8" Marine Zinc Alloy

Product description

This unit is a mil‑spec zinc alloy sacrificial anode intended for marine saltwater use.

The package contains one zinc anode sized for applications requiring a 1-7/8" anode. The component is formed from a zinc alloy that meets military specification standards for composition and performance in corrosive seawater environments.

Designed to be fitted to rudders or shafts, the anode corrodes in place to protect the surrounding metal. It is intended for routine replacement as the zinc is consumed during service.

Pros

  • Mil‑spec zinc alloy construction
  • Sized for 1-7/8" rudder/shaft mounting
  • Built for saltwater corrosion protection

Cons

  • Only suitable for saltwater environments
  • Will need periodic replacement
  • Supplied as a single anode

VerdictA straightforward, mil‑spec zinc anode sized for 1-7/8" rudder and shaft applications. Performs the basic job of sacrificial protection in saltwater environments. Simple, effective and easy to install — replace periodically as it degrades.
