VENTILATION AND DRAINAGE SYSTEMS
K - 1     ENGINE COMPARTMENT VENTILATION
C.   Engine Ventilation System Maintenance
All Four Winns® Vista models are equipped 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 National
Marine Manufacturers  Association, and the  American
Boat and Yacht Council.
Periodic inspection and cleaning of the ventilation ducts
isnecessarytoensureadequateaircirculation.     Abuildup
of leaves, twigs, or other debris can severely reduce ven-
tilation.  Be sure bilge water does not accumulate  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 of the 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.

The exhaust  ducting reaches to the  lower bilge area.
This provides adequate air movement while underway
and during bilge blower operation.

CABIN VENTILATION
B.   Forced Air Ventilation
All Vista cabins are equipped with deck hatches for ven-
tilation. The aft cabin window also opens to provide ven-
tilation. The cabin side windows (portlights) on the 248/
268 Vista may be opened to provide additional ventila-
tion.
AllFour Winns® Vista models areequippedwithanelec-
tric bilge blower.   The bilge blower provides the venti-
lation required prior to starting the engines and while at
idle.  See Section H  Electrical Systems for blower op-
eration instructions.
Failure to properly ventilate the boat while the
engines or generator are operating may permit
carbon monoxide to  accumulate inside of the
cabin. RefertoSection  E-2EngineExhaustand
Section B-2  Carbon Monoxide  for additional
information.
Before starting the engine(s) or generator, op-
erate the engine compartment bilge blower for
four (4) minutes.  Then check the engine com-
partment for gasoline vapors.  ALWAYS oper-
ate the  bilge blower while  the engines are  at
idle or the generator is in use. Failure to comply
could cause explosion and thereby inflict seri-
ous injury or death.
Screens for the forward deck hatches are available for
all Four Winns® boats. The screens are removable and
must be stored properly when not in use.
NOTICE
Fumes can  come from batteries  while charg-
ing. A concentration of hydrogen fumes can be
explosive under the right conditions.
Be sure deck hatches are secured while under-
way.  Damage to the hatch may  result.  Store
screens in a safe place to prevent damage.
NOTICE
A Gas Vapor  Detector is a monitor  which will
alert the operator of an accumulation of gaso-
line fumes in the engine compartment.  It is op-
tional on the 248/268 Vista and can be installed
by your  Four Winns®  dealer.   DO NOT  rely
solely on detectors or similar  equipment.  AL-
WAYS conduct a physical inspection of the en-
gine compartment.
K - 3     HULL DRAINAGE SYSTEMS
A.   Transom Drain

partment to allow water drainage.  When boat is out of
