In Oregon, a person must be at least 16 years old to legally operate a personal watercraft (PWC) without an adult on board. However, individuals aged 12 to 15 can operate a PWC if they have completed a state-approved boating safety course and are accompanied by an adult. It's important to follow all local regulations to ensure safety on the water.
