Most bottom paints require some maintenance. Proper maintenance is especially important when the boat is
in saltwater and not used for extended periods or after dry storage. If the hull bottom has been painted with
antifouling paint, contact your dealer for the recommended maintenance procedures.
Sacrificial Anodes
Sacrificial zinc anodes are installed on the inboard engines’ fresh water cooling system and on the transom.
The transom zinc is connected to the bonding system and protects the rudder assemblies, shaft logs and other
underwater hardware that is bonded. Additional zinc anodes are installed on the propeller shafts and the trim
tab planes.
The anodes are less noble than copper based alloys and aluminum and will deteriorate first, protecting the more
noble engine and underwater 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.
Boats stored in salt water will normally need to have the anodes replaced 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 zinc
anodes to be used and the specific installation 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. Harsh abrasive and chemical cleaners are not recommended 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, it
should be washed thoroughly with soap and water after each use.
At least once a season, wash and wax all exposed fiberglass surfaces. Use a high quality automotive or boat
wax. Follow the procedure recommended by the wax manufacturer. The 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 thus helping to prevent soiling and will extend the life of the gelcoat.
After the boat is exposed to the direct sunlight for a period of time, the color in the gelcoat tends to fade, dull
or chalk. A heavier buffing is required to bring the gelcoat 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.
DO NOT WAX NONSKID AREAS AS THIS COULD MAKE THEM SLIPPERY AND CONSE-
QUENTLY INCREASE THE POSSIBILITY OF INJURY.
USE EXTREME CARE WHEN WALKING ON WET GELCOAT SURFACES AS THEY ARE
SLIPPERY.
