Operating instructions

SAFETY INFORMATION 17
While underway, CO concentrations can increase by backdrafting or “the station
wagon effect”. Backdrafting is caused by factors such as relative wind direction,
speed, or the bow being too high. To prevent this, open canvas whenever possible
to provide positive airflow through the hull.
Boat houses, seawalls, and other boats in close proximity or confined areas can
contribute to increased CO levels. Operators must be aware that operation, moor-
ing, and anchoring in an area with other boats puts them in jeopardy of CO accu-
mulation from other sources. Likewise, a boat operator must be aware of how
exhaust from his boat will affect others. Operation of the engines while moored
may cause CO accumulation in your boat and those around you.
CONFINED AREAS
Be sure to provide adequate ventilation. If the windshield has vents, open them
before getting underway to increase positive air flow and decrease the chances
of CO accumulation.
Even with the best boat design and construction, CO may still accumulate in
enclosed or confined areas under certain conditions. Continually observe passen-
gers for symptoms of CO poisoning.
CO Detector
It is strongly recommended that you have CO detectors installed in boats with
canvas enclosures. Monitors are available from your dealer. Monitors should be
professionally installed and calibrated.
NOTE: A CO detector is not a gas fuel vapor detector. Gas fuel vapor detectors
do not monitor the buildup of CO in an enclosed area.

WARNING
Backdrafting! Under certain conditions, moving air currents can direct poi-
sonous CO fumes into boat. These fumes can accumulate to dangerous
levels without proper airflow. Provide adequate ventilation, redistribute
the load or bring boat out of high bow angle.
