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.
Screens.and.blinds.for.the.forward.deck.hatches.are..
a standard feature. This “layered” deck hatch system
allows.the.screens.and.blinds.to.be.slid.to.the.desired.
position.with.ease..Also,.storage.for.the.screens.and.
blinds.are.built.into.the.screen/sun/shade.system...
See.Figure.K-1..
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.
NOTICE
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 Vista
®
models. DO NOT rely solely on detectors or
similar equipment. ALWAYS conduct a
physical inspection of the engine compartment.
