A muffler is required for a boat when it is equipped with an internal combustion engine, particularly to comply with noise regulations and reduce engine noise for both environmental and safety reasons. Many jurisdictions have specific laws regarding noise levels for boats, so a muffler helps ensure compliance with these regulations. Additionally, a muffler can help improve engine performance by reducing back pressure. Always check local regulations to determine specific requirements.
