Electrolysis And Galvanic Protection - Hunter 386 Owner's Manual

ELECTROLYSIS AND GALVANIC PROTECTION

Salt water allows electric current to flow from
anodic to cathodic material. For any two
metals from two components, their relative
positions in the galvanic rating table, will
determine which loses material (the anode)
and which remains largely undisturbed (the
cathode). The distance between the two
metals on the galvanic table determines the
rate of wear. Thus a sacrificial zinc anode is
often fitted to the underwater area of a boat
to attract any destructive currents away from
bronze or steel propeller shafts, for example.
It is not enough to know that your boat does
not suffer from electrolysis; a newcomer in
the adjacent marina berth may start a too-
TEAK CARE (240,260,and 270 ONLY)
Teak wood is a high quality, extremely
durable wood with high oil content. In order
to help you protect the original beauty of
your teak interior, we have sealed the wood
with a 3 to 4 coat system of high quality
Seafin Teak Oil, manufactured by Dalys.
This material is penetrating oil that dries to a
low sheen to seal and protect the wood from

When woodwork is damaged from scrapes
or abrasions that go into or thru the finish,
take the following steps:
1. Take 180 to 200 grit wet/dry sand paper
to smooth out rough spots.
2. Wipe clean of dust and dirt with a clean
rag. Note: before applying oil, wood surface
must be dry.
3. Wipe or brush on oil, allow to penetrate 5-
15 minutes while surface is still wet.
4. Sand until smooth with 400A wet/dry
sandpaper.
5. Wipe dry with a clean rag. Allow 8-12
hours drying time.
friendly association with metal components
on it. An easy place to fit an anode is on the
propeller shaft, or covering the propeller nut.
The anode should not be painted; this would
render it ineffective.
To prevent electrolysis in seawater, the
difference between the voltages of the two
adjacent metals should not exceed 0.20 V.
For example, zinc and carbon steel used
together risk corrosion, while lead and active
stainless steel are compatible. Metals with a
high voltage corrode faster and need a
larger area to diffuse the electrochemical
reaction.

This procedure may be repeated as many
times as needed to bring damaged area
back to its original finish. If you have trouble
with getting the same sheen, you may use a
soaked and wrung out cloth to apply a very
light coat to get an even sheen.
