Annually conduct a detailed inspection of fuel system components, especially those hidden
from routine inspection. Replace any fittings, deteriorated hoses, clamps or connections
immediately. Fuel filter/water separators should be replaced at least annually.

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 rust
and 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.

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.
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
