Sacrificial Anodes (Zincs) - Bayliner 3788 Owner's Manual

8 CHAPTER 2: FEATURES / SYSTEMS

Sacrificial Anodes (Zincs)

Your yacht is equipped with sacrificial anodes to protect underwater metal parts from excessive deterioration. Sacri-
ficial anodes should be checked regularly and replaced if they have deteriorated more than 70%. There are many fac-
tors that determine the rate at which sacrificial anodes deteriorate, including :
• Water temperature
• Salinity
• Water pollution
Stray current from the boat or dock may cause complete deterioration in just a few weeks. If there is rapid anode
deterioration, measure electrolytic corrosion around your yacht with a corrosion test meter. If sacrificial anodes are
not bonded correctly, they will not provide protection.
