Exhaust & Carbon Dioxide - Regal 53 SC Owner's Manual

EXHAUST & CARBON
MONOXIDE
Carbon monoxide (CO) in exhaust can be hazardous.
especially from gasoline engines, gasoline generators,
grills, stoves, space heaters and on a much smaller
degree diesel engines.
CO is a natural by-product of the gasoline engine using
an artifi cial spark . Diesels on the other hand detonate fuel
using pressure and temperature. Looking at the two engines
another way, gasoline engines use much more oxygen up
in the combustion process which contributes to a much
higher CO build-up. Although diesels do produce a small
amount of CO the combustion process operates with
much greater amounts of oxygen which the end result is
a much lower CO level.
In conclusion, even though your vessel uses diesel
propulsion ensure that you read the information and
follow all the recommendations regarding CO as
if it were gasoline powered. Familiarize your crew,
passengers and yourself with the sources, symptoms
and possible effects of carbon monoxide poisoning.
Remember that boats in the same general vicinity can
cause your vessel to accumulate dangerous CO levels
in the cabin and or under the hardtop due to the above
conditions and sources.
WARNING
!
AVOID SERIOUS INJURY OR DEATH
FROM CO POISONING!
DO NOT OPERATE THE BOAT WITH PEOPLE
HOLDING ON TO THE SWIM PLATFORM
OR WITH PEOPLE IN THE WATER.
For safety sake avoid the following:
1. Do not park by other boats with their engine idling or
generator cycling for an extended period of time .
2. Do not disable the carbon monoxide alarms that come
with your Regal boat. Test the units in accordance with
the alarm manufacturers instructions.
3. Do not operate an engine for extended periods of time
while in a confi ned area or where exhaust outlets face a
sea wall or bulkhead.
4. Do not operate the engine for an extended period
of time with the canvas in the upright and installed
position.
5. Have the engine exhaust system inspected when the
boat is in for service.
6. Persons sleeping can easily be overcome by carbon
monoxide without realizing it. Do not sleep on board
while an engine or generator is running close-by.
7. Do not operate your vessel for extended periods with the
bow up in slow cruise conditions especially close behind a
vessel being towed or one operating at slow speeds.
8. When underway open all hatches, windshield vents,
and main cabin entry door to allow proper airfl ow from
bow to stern.
9. Never use a propane or LPG gas grill or stove in an
enclosed area for a heat source.
Note: A yellow fl ame verses a blue fl ame is a sign of poor
combustion in a cooking device.
