Zinc Anodes, Aluminum Anodes & Magnesium Anodes
Which anode material is used for what application?
ZINC Anodes
- For use in salt water only
- Not recommended for use in fresh water
ALUMINUM Anodes
- For use in salt and brackish water
- Not recommended for use in fresh water
- Proven to last longer than zinc due to increased capacity
MAGNESIUM Anodes
- For use in fresh water only
- Not recommended for use in salt and brackish water
- The only alloy proven to protect your boat in feresh water
Sacrificial Anodes are placed on hulls, propeller shafts, rudders,
trim tabs, outboard engines, stern drives, and in the cooling
system of most inboard engines to protect metal parts from galvanic
corrosion.
Galvanic corrosion occurs when dissimilar metals, such as an
aluminum stern drive and a bronze through-hull, are placed in an
electrolyte solution such as seawater. Dissimilar metals are those
metals which have different corrosion potential (measured in volts)
as determined by the Galvanic Series, and the most common scenario
in boating is current passing from the more noble bronze to the
less noble aluminum. This transfer of current results in
deterioration of the less noble metal. The addition of a zinc
actually increases current activity between the metals, but because
zinc is the least noble of the three metals in this example,
corrosion damage is primarily confined to the zinc itself when
properly installed.
Marine anodes are available in zinc, aluminum and magnesium metals
to protect different hardware items and other metal boat
components. Plate, tear drop, rudder, shaft, tapered, mercury
outdrive (specifically designed for use with Mercury engines), zinc
pencils, donut collar, Johnson-Evinrude (for use with
Johnson-Evinrude engines), weld-on, and other shapes and styles.
The corrosion resistance results provided by proper application of
boat zinc is incredible and will save time and money in the long
run.

Marine Engine application:
Marine engine zinc Anode for all YACHT engines. Zincs should be
replaced every season or after 2/3 of zinc has eroded, which ever
happens first. These are pre cut zinc engine anodes complete with
brass plug and zinc.

Can be also customized by buyer
- The loss of water heater anode protection,
- The accumulation of sediment at the bottom of the tank,
- Having a water heater that is not dielectrically connected
correctly to the hot and cold lines.
