OMPARTMENT
The fuel tank compartments need to be rinsed periodically especially when used in a salt-
water environment. Dirt accumulation attracts salt, creating salt crystals. Salt crystals can corrode
most metal surfaces if left untreated over a period of time. To help protect your fuel tank from
corrosion, rinse the compartment with
fresh water. After rinsing, make sure all water is drained
from the compartments. Remove the access plates from fuel tank lids and inspect this area for
leaks or unsecured lines.
The access plates on your fuel tank lids keep the fuel compartments sealed. Over time, the
opening and closing of these plates causes the o-rings to wear out. Replace these o-rings as
necessary to maintain the watertight integrity of the plates.

HOWER
S
UMP
A shower in the head compartment drains into a contained “sump” which is used to prevent
hair, soap, scum and bacteria from accumulating in the bilge and creating odors. This sump
should be cleaned regularly. The sump pump box contains a filter. Remove the filter and rinse
with water to clean. The filter should always be installed when using the shower to prevent the
sump pump from becoming clogged.

ATTERIES
Proper battery power is essential to the operation of your vessel. For this reason, Grady-White
has carefully chosen a battery with cranking ability and reserve capacity sufficient to meet your
needs. The factory installed Deka Marine Master 27M6 battery is a maintenance free battery. This
battery utilizes an exclusive demineralized electrolyte and maintenance free calcium alloy grids.
These features reduce water loss and extend the life of the battery. However, this battery is
maintenance accessible in the unlikely event a charging malfunction occurs. Grady-White
recommends the Deka 27M6 product for all replacement applications. If your boat is equipped
with batteries not installed at the factory, consult with the battery manufacturer for proper care
and maintenance instructions and the engine manufacturer for appropriate battery specifications.
Wet cell batteries must be secured in a non-metallic tray to contain electrolyte spills. An
insulated boot should cover battery terminals. Keep terminals clean by scrubbing them with a stiff
brush and a mixture of baking soda and water. Afterwards, apply a light coat of grease or
corrosion preventative.
Batteries contain sulfuric acid, a harmful and potentially volatile chemical. When handling
batteries, exercise caution and follow these guidelines.
• Avoid contact between skin, eyes, or clothing and sulfuric acid.
• Protective gloves, eye wear, and clothing should be worn when servicing to minimize risk to
yourself.
• Batteries produce explosive gases. Keep sparks, flames and cigarettes away. Ventilate when
charging or using in an enclosed space.
• Keep out of reach of children.
