Sacrificial Anodes
Sacrificial zinc anodes are installed on the
trim tabs, transom and outboard engines.
The transom anode is connected to the
bonding system and protects the underwater
hardware that is bonded.
The anodes are less noble than copper
based alloys and aluminum and will deterio-
rate first, protecting the more noble under-
water hardware against galvanic corrosion.
Anodes should be checked monthly and
changed when they are 75% of their original
size. When replacing the anodes, make sure
the contact surfaces are clean, shiny metal
and free of paint and corrosion. Never paint
over the anode or protect it.
Boats stored in saltwater will require anodes
to be replaced at least every 6 months to
one year. Anodes requiring replacement
more frequently may indicate a stray current
problem within the boat or at the slip or
marina. Anodes that do not need to be
replaced after one year may not be providing
the proper protection. Loose or low quality
anodes could be the problem. Contact your
dealer for the proper size and type of
anodes to be used and the specific installa-
tion procedure.
Fiberglass Gelcoat Surfaces
Normal maintenance requires only washing
with mild soap and water. A stiff brush can
be used on the nonskid areas. Kerosene or
commercially prepared products will remove
oil and tar which could be a problem on
trailered boats. DO NOT use harsh abrasive
and chemical cleaners because they can
damage or dull the gelcoat, reducing its life
and making it more susceptible to stains.
When the boat is used in saltwater, wash it
thoroughly with soap and water after each
use.
Sudden changes in temperature can affect
gelcoat. When planning on moving your boat
from outdoors to a heated location, allow the
change of temperature to be gradual. Warm
the location slowly after the boat is brought
inside to allow the boat to change tempera-
ture slowly as the location is warmed.
Or, if
you are moving your boat from a warmer
area to a colder one, wait for the tempera-
ture to be closer to the temperature of the
warmer area or allow the warmer area and
the boat to cool down.
At least once a season, wash and wax all
exposed fiberglass surfaces. Use a high
quality marine wax ONLY. Follow the proce-
dure recommended by the wax manufac-
turer. Washing and waxing of your boat will
have the same beneficial effects as they
have on an automobile finish. The wax will
fill minute scratches and pores which help
prevent soiling and will extend the life of the
gelcoat.
After the boat is exposed to the direct sun-
light for a period of time, the color in the gel-
coat tends to fade, dull or chalk from
oxidation of the gel. This condition will be
more apparent with dark colors, which
require more frequent maintenance. A
heavier buffing is required to bring the gel-
coat back to its original luster. For power
cleaning use a light cleaner. To clean the
boat by hand, use a heavier automotive
cleaner. Before cleaning the surfaces, read
the instructions given with the cleaner. After
cleaning the surfaces, apply wax and polish
all fiberglass surfaces except the nonskid
areas.
If the fiberglass should become damaged
and need repair, contact your dealer for an
authorized repair person to make the
repairs.
NOTICE
Use only a good quality marine wax
(carnauba or equivalent). Never use a
polymer or silicone based product on
gelcoat surfaces as these products
can cause irreparable damage and
staining.
