Operation
Corrosion Protection
Galvanic corrosion (electrolysis), is the break-up of metals do to the effects of electrolytic
action. When two dissimilar metals are immersed in a conductive fluid such as salt water,
an electric current is produced, similar to that of a battery. As the current flows, it takes
with it tiny bits of the softer metal. If not stopped, a great deal of damage can occur.
If you operate your boat in salt or brackish waters, you should have your boat equipped
with a transom mounted zinc anode to prevent damage to the parts coming in contact
with the water. The zinc anode being the softer metal will deteriorate and erode much
faster than the other metals in the boat. Inspect the anode periodically and replace as
needed. Consult your local Axis dealer for this part.
Saltwater Corrosion
If you use your boat in salt or brackish water, wash the entire boat, including trailer and
tower (if fitted), thoroughly with a mild detergent and rinse with fresh water after
EVERY USE. Apply a corrosion inhibitor to all hardware regularly. Consult your dealer
for products suitable for the marine saltwater environment and proper usage instructions.
Axis strongly recommends freshwater internal engine flushing after using the boat in salt,
polluted or brackish waters. Flush the entire cooling system with fresh water for at least
five minutes after use in these waters. See your Axis dealer for appropriate flushing
devices and additives.
Salt water is commonly very harsh on all components of boat.
Saltwater corrosion is not covered under your Axis or engine
manufacturer warranties. It is the boat owner’s responsibility
to understand and ensure they have taken proper precautions
to safeguard boat.
