Dangerous Activity
N. Cabin Appliances
Boats having fuel burning appliances in accommo-
dation areas should be provided with adequate venti-
lation and the appliance should be maintained
to function properly.
O. Air Conditioning (Applicable Models Only)
Lack of system maintenance may cause CO to be
brought into the air-conditioned spaces by the air con-
ditioner. If applicable, please refer to the air condition-
er manufacturer’s literature for additional information.
Please consult with your Four Winns Dealer regarding
availability.
P. Ventilation of Accommodation (Occupied)
Spaces
Accommodation spaces need to be ventilated to in-
troduce fresh air into the spaces. Ventilation methods
(e.g., windows, hatches, doors, and blow ers) used to
accomplish this may, under certain conditions, bring
hazardous levels of CO into the occupied spaces.
Care should be taken to be aware of all prevailing
conditions when using these ventilating methods.
Q. Running of Engines in Idle
Engines running in idle exhaust carbon monoxide that
can accumulate near the hull of the boat. Do not stand
or swim near the engine exhaust or outdrive when
engine is idling or generator is running.
R. Altitude and Sea Conditions
Operation at altitudes greater than 5,000 feet con-
tributes to inefficient engine performance and may
require adjustments to the ignition systems, fuel sys-
tems, or changing the propeller’s size or gear ratio.
1. Failure to make adjustments to ignition sys tems
and/or fuel systems for altitude conditions may
cause an increase in CO production.

with Following Wind
6. Be aware that cockpit and deck drains can be a
source of CO ingress into boats, especially boats
with cockpit or decks enclosed with canvas or
permanent boat structures.
L. Accumulation of Exhaust Gases-
Swim Platform
When the propulsion engine or generator is running,
CO is produced and may remain in the vicinity of the
exhaust outlet (including underwater exhaust outlets).
1. Do not occupy aft lounging area(s) or swim
platform.
2. Do not swim under or around swim platform.
3. Do not swim in the vicinity of the exhaust outlet.
Refer to Figure B13.

M. Dangerous Activity -
“Teak Surfing”/“Dragging”
Do not sit on, occupy or hang on any stern append-
ages (e.g., swim platforms, boarding ladders, etc.)
while underway. Do not body surf, commonly known
as “teak surfing” or “dragging”, etc., in the wake of
the boat. Do not tow persons in close proximity to the
stern of the boat. See Figure B14. This activity can
also increase the possibility of injury due to contact
with a rotating propeller.
