LOCATION AND DESCRIPTION OF MAJOR COMPONENTS (Contd)
Q Battery Compartment -- Consists of three subcompartments as follows:
Port side compartment: Consists of two batteries, lubricity filter, inspection light, master fuse link,
blocking diode, and utility connection plug for the FM200 fire system alarm or inspection light.
Center compartment: Consists of fuel tank, fuel filler cap, two fuel water separators, port and starboard
fuel shut-off valves, and master fuel shut-off valve located below and between the port and starboard
fuel shut-off valves.
Starboard side compartment: Consists of master battery switch, two batteries, lubricity filter, blocking
diode, emergency link solenoid, master fuse link, and a NATO slave receptacle that provides/receives
electrical power for starting the boat when batteries are not charged.
R Engine Compartment -- Consists of two diesel engines and transmissions for port side and
starboard side. Also contains a fire extinguisher system, keel cooler plumbing, exhaust hoses and tubes,
bilge pump, and coolant reservoirs.
S Drive Shafts -- Located under the aft cockpit, the two drive shafts transfer power from the
transmission to the hydrojets.
T Hydrojet Inlet Grills -- Located near the rear and under boat, the hydrojet inlet grills provide a
screen system to help protect the hydrojets from ingesting objects that may cause damage.
U Hydrojets -- Consist of two hydrojet propulsion units with directional nozzles and scoops. The
propulsion units propel and steer the boat. The hydrojets supply a raw water cooling system for the boat.
V Fire Extinguisher System -- The fire extinguisher bottle is located along the port side hull wall,
centered under the port side engine compartment hatch cover. If a fire is detected, the contents of the
fire bottle will automatically be dispersed.
W Keel Coolers -- Centrally located underneath the boat, the keel coolers are part of a closed-loop
cooling system that cools the engines, engine oil, exhaust manifolds, and turbocharger. The keel coolers
have a protective grill mounted underneath to help prevent damage.
