Ventilation and Drainage Systems
K - 1 ENGINE COMPARTMENT
VENTILATION
C. Engine Ventilation System Maintenance
Periodic inspection and cleaning of the ventilation
ducts is necessary to ensure adequate air circulation.
A buildup of leaves, twigs, or other debris can severe-
ly reduce ventilation. Be sure bilge water does not
accumulate to a level that would obstruct the ventila-
tion ducts.
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 US Coast
Guard, the National Marine Manufacturers Associa-
tion, and the American Boat and Yacht Council.
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.
A. Natural Ventilation System
This system includes air intake and exhaust com-
ponents. The exhaust ducting reaches to the lower
bilge area. This provides adequate air movement
while underway and during bilge blower operation.
K - 2 CABIN VENTILATION
B. Forced Air Ventilation
The 258 and 278 Vista cabins are equipped with a
®
deck hatch for ventilation. The aft cabin window also
opens to provide ventilation. The cabin side windows

provide additional ventilation.
Failure to properly ventilate the boat while the
engines or generator are operating may permit
carbon monoxide to accumulate inside of the
cabin. Refer to Section E- - Engine Exhaust
and Section B- - Carbon Monoxide for
additional information.
Before starting the engine(s) or generator,
operate the engine compartment bilge blower
for four () minutes. Then check the engine
compartment for gasoline vapors. ALWAYS
operate the bilge blower while the engines are
at idle or the generator is in use. Failure to
comply could cause explosion and thereby
inflict serious injury or death.
A screen for the forward deck hatch is a standard
feature. The screen is removable and must be stored
properly when not in use.
NOTICE
Fumes can come from batteries while
charging. A concentration of hydrogen fumes
can be explosive under the right conditions.
Ensure to follow the above warning.
Be sure deck hatch is secured while underway.
Damage to the hatch may result. When not in
use store screen in a safe place to prevent
damage.
NOTICE
K - 3 HULL DRAINAGE SYSTEMS
A. Transom Drain
A gas vapor detector is a monitor which will
alert the operator of an accumulation of
gasoline fumes in the engine compartment.
It is optionally available on the and
A transom drain with plug is provided in the engine
compartment to allow water drainage. When boat is
out of the water, the boat and cradle should be
positioned so any bilge water accumulation during dry
storage will flow towards the transom.
Vista models. DO NOT rely solely on
®
detectors or similar equipment. ALWAYS
conduct a physical inspection of the engine
compartment.
