General
The amount of maintenance required to keep your boat operating properly and to maintain the
appearance is dependent on how the boat is used, amount of usage, salt or fresh water, geographic
location, etc. While proper maintenance of your boat is a source of pride, it is also key to maintaining
your boat’s value.
Some basic maintenance items are covered in this chapter. Other manuals in your Owner’s
Packet contain important additional information regarding the use and maintenance of your boats
other systems.
Keep the bilge area clean and dry. Leaks found early and corrected will less likely cause damage.
Do not allow grease, grime, and dirt to build up.
Exterior Fiberglass Finish
The exterior finish of your Grady-White is a thin layer of resin with a finished color pigment
called gel-coat. It is used for cosmetic purposes and makes routine maintenance relatively simple.
Although gel-coat has a hard smooth surface, it does contain microscopic pores that will allow
surface discoloration if not kept clean.
Maintenance
Normal exterior finish maintenance of your Grady-White is similar to the care you would give
your automobile. Do not use caustic, highly alkaline cleaners or those containing ammonia.
These cleaning agents may darken gel-coat. The resulting stain is a chemical reaction and can
be removed with a rubbing compound or by light sanding with 400 grit followed by waxing.
Also, using common household bleach (chlorine) may damage the gel-coat finish just like
bleach can damage clothing with colors. Bleach impacts solid colors by causing blushing or
fading and for this reason should not be used on gel-coat.
Cleaning
The best way to prevent discoloration and soil build-up is to hose the boat with fresh water
after each outing or on a regular basis. This build-up is the result of use and environmental
pollutants. Clean the boat regularly with a mild household detergent and plenty of fresh water.
Avoid strong detergents, citrus based cleaners, or bleaches. These products are potentially
harmful to the appearance and durability of your boat’s gel-coat. Always read the label before
using any cleaning product to make sure it says safe for use on fiberglass finishes. Use a
sponge on smooth surfaces and the deck. A brush can be used on the nonskid areas. Use fresh
water to rinse away all grime and residue.
