Are personal watercraft exempt from power ventilation requirements?

• A. Yes
• B. No
• C. Only if diesel
• D. Only if not in enclosed space

Answer: (A)

Power ventilation is required to prevent the buildup of fuel vapors and carbon monoxide in enclosed engine spaces. Personal watercraft do not have a true enclosed engine space—the engine is exposed to outside air and there isn’t a sealed area that could trap fumes. Because of this, PWCs are exempt from the power ventilation requirement. The other options don’t fit because the exemption isn’t conditional on diesel versus gasoline or on being in an enclosed space.
