generally require replacement about once a year.
(In salt water areas, replace every six (6) months).
The need to replace anodes more frequently may
indicate a stray current problem within the boat or
at the slip or mooring. If zinc anodes do not need
replacing after one year, they may not be providing
proper protection. Loose anodes or low-grade zinc
may be the problem.
! CAUTION
Replace zinc sacrificial anodes if they are corroded
50% or more.
DO NOT PAINT BETWEEN THE ZINC AND THE
METAL IT CONTACTS, AND DO NOT PAINT
OVER THE ZINC.
When an AC shore power system is connected to
the boat, the underwater metal fittings will, in effect,
be connected through the water to grounded metals
ashore. The zincs will be consumed at a faster rate
unless the marina maintains a protective system to
prevent this. In this case, hanging a zinc in the water
bonded to the metal outlet box on the dock will
reduce zinc loss on the boat. DO NOT connect
this zinc to the boat's ground system.
