VENTILATION & DRAINAGE
H - 1 ENGINE COMPARTMENT VENTILATION
All Carver boats are equ ipped with engine compartment
ventilation. This system is designed to meet or exceed
the requirements (in effect at the time of manufacture)
of the U.S. Coast Guard, the Boating Industry Associa­
tion, and the American Boat and Yacht Council.
A. Gravity Ventilation System
This system includes air intake and exhaust compo­
nents. The exhaust ducting reaches to the lower bilge
area. This provides adequate air movement while
underway and during bilge blower operation.
B. Forced Air Ventilation
All Carver boats are equipped with an electric bilge
blower. The bilge blower provides the ventilation re­
quired priorto starting the engines and while at idle. See
section E for blower operation instructions.
C. Engine Compartment Ventilation System Main­
tenance
Periodic inspection and cleaning of the ventilation ducts
is necessary to ensure adequate air circulation. A build­
up of leaves, twigs, or other debris can severely reduce
ventilation. Be su re bilge water does not accu mu late to
a level that would obstruct the ventilation ducts.
Blower operation can be tested by placing a hand over
the vents. DO NOT rely on the sound ofthe blower. Be
sure a substantial amount of air is being exhausted by
the bilge blower. Check the bilge blower system often,
preferably before each cruise.
Should blower noise and vibration be excessive, loos­
ening the bilge blower mounting screws and then re­
tightening evenly usually reduces noise considerably.
H - 2 CABIN VENTILATION
Certain cabin side windows on Carver boats are de­
signed to slide open to provide adequate cabin ventila­
tion. Certain cabin side windows have screens pro­
vided. Screens fortheforward deck hatch are provided
with larger model Carver boats.
In time, the black coloration on certain deck hatch and
port hole assemblies may become lighter in color. This
is due to the surface oils that were applied to the plastic
are being removed due to exposure, this is normal. The
deep, rich black color can easily be restored by periodic
applications of mineral oil or silicone lubricant.
Some windshields have opening vents. Be sure the
windshield adjusters are secured properly, otherwise
undue strain can be placed

H - 3 HULL DRAINAGE SYSTEMS
A. Garboard Drain
A garboard drain is provided near the keel to allow water
drainage while the boat is in dry dock. The boat and
cradle should be positioned so any bilge water accumu­
lation during dry storage will flow towards the garboard
drain. The garboard drain is usually in the engine
compartment or near the transom.
