Chapter 6: Maintenance and Service

Fuel Tank Compartment

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 the 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.

Shower Sump

The shower in the head compartment and condensation from the air conditioning drain 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.

Batteries

Proper battery power is essential to the operation of your vessel. For this reason, Grady-White has

carefully chosen batteries with cranking ability and reserve capacity sufficient to meet your needs. Grady-
White uses Deka Intimidator 8A27M brand marine batteries. 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. Replacements batteries should always
be of the same brand, model, age and size. Never mix different types of batteries.

The Intimidator 8A27M is an absorbed glass mat (AGM) battery that is completely spill proof and

maintenance free. AGM batteries recharge faster than conventional batteries and have a higher tolerance to
deep discharge for more severe applications. AGM batteries are subject to permanent damage if used with a
charging system not compatible with this technology, which should be considered if using a charging system
other than those installed on your boat.

Batteries contain electrolytes and acids that can be harmful and volatile. They can also present an

electrical hazard. When handling or servicing batteries, exercise caution and follow these guidelines.

• Avoid contact with skin, eyes, and clothing. Protective gloves and eye wear should be worn when

servicing to minimize risk.

• Batteries can produce explosive gases. Ventilate when charging. Keep sparks, flames and

cigarettes away at all times.

• An insulated boot should cover battery terminals in normal use. Never allow anything metal to

bridge between the positive and negative terminals which could arc or create a burn hazard.

• Keep battery 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 should be secured to minimize movement when the boat is in use.
