Galvanic Corrosion
NOTE: DAMAGE DUE TO CORROSION IS NOT COVERED UNDER
WARRANTY!
Galvanic corrosion (electrolysis) is the decomposition of metal
due to the effects of electrolytic action. When two (2) dissimilar
metals are immersed in a conductive fluid (e.g., salt water), an
electric current is produced, much like the action of a battery. As
the current flows, it takes with it tiny bits of the softer metal. If
left unchecked, severe damage may occur over time. If the boat
is operated in salt, polluted or brackish waters, even temporarily,
the boat should be equipped with a transom-mounted aluminum
anodes to prevent damage to those metal parts coming in
contact with salt water.
The aluminum is, by design, self-sacrificing. It is slowly
eroded away by electrolytic action and requires periodic
inspection for deterioration.
When the aluminum has eroded to approximately one-half (1/2)
of its original size, it must be replaced to continue protection,
or damage to other metal parts may result. Aviara boats come
equipped with aluminum anodes. DAMAGE DUE TO CORROSION
IS NOT COVERED UNDER WARRANTY!
Saltwater Care &
Maintenance
Saltwater or brackish water can deteriorate the condition of a
boat much faster than freshwater. To maintain the condition,
appearance and functionality of boats used in salt water:
1. Flush the engine with fresh water in accordance with the
Ilmor or Mercury Engine Owner’s Manual, where equipped
(10 minutes minimum).
2. Rinse the boat with fresh water after each use in salt water:
• Bilge
• Hull and deck including all underwater gear
