Shut the engine off when the boat nears the skier so there is no danger from the propeller. When the
engine is idling, even in neutral, the propeller may still be turning and can injure an unwary skier, or
entangle and cut the towline. In addition, anytime the engine is on, carbon monoxide poisoning is a
danger. Repeated or prolonged exposure, even in the open air environment, can cause fainting and
subsequent drowning. If a skier falls and is injured, proceed with caution. Any injury may be
aggravated by trying to pull the person from the water and onto the boat. Get into the water to support
the skier until help arrives or the nature of the injury is known. .....
Since skiing activities often involve persons being in and around the boat stern, near or on the
swimstep, or in the water adjacent to the stern, operators should make sure that the engine is off so
that no one is poisoned by the fumes from an idling engine.
Water ski lines are typically long enough to minimize exposure to exhaust fumes, but those who ski on
shorter lines risk increased exposure. .....
