This fish-shaped zinc anode is a portable overboard sacrificial anode designed to provide temporary corrosion protection for boats at dock or anchor. Commonly referred to as a fish anode, it connects via cable and clamp directly to the vessels bonding system.

Ideal for protecting underwater metals when shore power or marina electrical conditions may increase stray current corrosion.

Key Features

Marine-grade zinc construction (saltwater use)
Fish-shaped design for increased surface area
Includes cable and alligator clamp
Portable, no installation required
Helps reduce stray current corrosion

Application

Used for:

Boats at dock or marina
Temporary corrosion protection
Supplementing onboard anode systems

Common on:

Inboard and sterndrive boats
Boats in marinas with electrical activity

When to Replace

Anode is 50% consumed or more
Heavy pitting or uneven wear
Cable or clamp damage

Usage Notes

Submerge fully in water
Attach clamp to clean bonding point
Use while docked (not while underway)
Do not paint anode

Parts Desk Insight

Fish anodes are a backup protection tool, not a replacement for installed anodes. Theyre especially useful in marinas where stray current corrosion can vary depending on neighboring boats and shore power conditions.
